본 발명은 급성 및 퇴행성 뇌신경계 질환의 예방 및 치료에 유용한 하기 화학식Ⅰ로 표시되는 5-(치환된 페닐알킬)아미노살리실산 화합물의 제조방법에 관한 것이다.The present invention relates to a process for the preparation of 5- (substituted phenylalkyl) aminosalicylic acid compounds represented by the following formula (I) useful for the prevention and treatment of acute and degenerative neurological diseases.
<화학식Ⅰ><Formula I>
상기 식 중에서, R은 수소 또는 할로겐(halogen)기, 할로알킬(haloalkyl)기, 니트로(nitro)기, 알킬(alkyl)기, 아릴(aryl)기, 알콕시(alkoxy)기, 아민(amine)기이며, n은 1또는 2로 표현되는 화합물이다. In the above formula, R is a hydrogen or halogen group, haloalkyl group, nitro group, alkyl group, aryl group, alkoxy group, amine group And n is a compound represented by 1 or 2.
대한민국 공개특허 제2003-0058934호에는 5-(치환된 페닐알킬)아미노살리실산화합물이 급성 및 퇴행성 뇌신경계 질환의 예방 및 치료에 유용한 물질로써, 알츠하이머병, 파킨슨씨병 및 헌팅턴씨병 등의 퇴행성 뇌신경계 질환, 간질 등의 경련성 뇌신경계 질환과 뇌졸중 등의 허혈성 뇌신경계 질환의 예방 및 치료 등에 유효한 것으로 기재되어 있어 상기 화합물의 제조는 학계 및 산업계의 관심이 크다.Korean Unexamined Patent Publication No. 2003-0058934 discloses 5- (substituted phenylalkyl) aminosalicylic acid compound as a useful substance for the prevention and treatment of acute and degenerative neurological diseases, including degenerative neurological diseases such as Alzheimer's disease, Parkinson's disease and Huntington's disease. It has been described as effective for the prevention and treatment of convulsive neurological diseases such as epilepsy and stroke, and ischemic cerebral nervous system diseases such as stroke.
상기 화합물 제조에 대해서 대한민국 공개특허 제2003-0058934호에 5-(4-나이트로페네틸)아미노살리실산과 5-(4-나이트로페닐프로필)아미노살리실산을 제조 하는 방법이 기재되어 있으며 상세하게는 하기 반응식 I에 도시한 바와 같다.Regarding the preparation of the compound, Korean Patent Publication No. 2003-0058934 discloses a method for preparing 5- (4-nitrophenethyl) aminosalicylic acid and 5- (4-nitrophenylpropyl) aminosalicylic acid. As shown in Scheme I below.
<반응식 I>Scheme I
상기 반응식 I에서는, 5-(4-나이트로페네틸)아미노살리실산과 5-(4-나이트로페닐프로필)아미노살리실산을 아미노살리실산과 2-(4-나이트로페닐)에틸브로마이드 또는 3-(4-나이트로페닐)프로필브로마이드 화합물과의 트리에틸아민과 디메틸포름아마이드 용매 하에서 반응시켜 치환 반응 메커니즘으로 목적물을 제조하는 방법을 보여주고 있다.In Scheme I, 5- (4-nitrophenethyl) aminosalicylic acid and 5- (4-nitrophenylpropyl) aminosalicylic acid are substituted with aminosalicylic acid and 2- (4-nitrophenyl) ethylbromide or 3- (4 Triethylamine with a nitrophenyl) propyl bromide compound and a dimethylformamide solvent are shown to prepare a target product as a substitution reaction mechanism.
그러나 상기 방법으로 제조되는 경우 출발물질인 2-(4-나이트로페닐)에틸브로마이드 또는 3-(4-나이트로페닐)프로필브로마이드 화합물이 아미노살리실산 중의 아민기가 염기로 작용하여 5-(4-나이트로페네틸)아미노살리실산 또는 3-(4-나이트로페닐)프로필브로마이드가 치환 반응(substitution reaction)이 아닌 수소화 브롬으로 제거 반응(elimination reaction) 되어, 하기 화학식Ⅲ의 표현되는 나이트로스티렌(4-nitrostyrene) 혹은 1-알릴-4-나이트로벤젠(1-allyl-4-nitrobenze ne)으로 생성되는 문제점이 있다. 이와 같이 생성된 하기 화학식Ⅲ의 모노머(monom er)는 일반적인 재결정법으로는 제거가 용이하지 않으며, 또한 연속적으로 중합반응(polymerization)이 진행되어 많은 중합체 및 올리고머, 다이머 등 많은 불순물이 생성되고 이를 제거하기 위해서는 컬럼 혹은 증류 등의 복잡한 정제 공정을 거쳐야 하기 때문에, 이에 따른 수율의 감소, 낮은 순도의 목적 화합물 제조 및 제조비용의 상승 등으로 상업적 제조방법으로는 여러 가지 문제점을 내포하고 있다.However, when prepared by the above method, the starting material 2- (4-nitrophenyl) ethylbromide or 3- (4-nitrophenyl) propylbromide compound acts as a base for the amine group in the aminosalicylic acid, resulting in 5- (4-knight Lofenethyl) aminosalicylic acid or 3- (4-nitrophenyl) propylbromide is removed by nitric hydride bromine instead of substitution reaction, whereby nitrostyrene (4- nitrostyrene) or 1-allyl-4-nitrobenzene (1-allyl-4-nitrobenze ne) is a problem that is produced. The monomer of the general formula (III) thus produced is not easy to be removed by a general recrystallization method, and also polymerization is continuously performed to generate a large number of impurities such as many polymers, oligomers, and dimers, and remove them. In order to perform a complex purification process such as column or distillation, there are various problems in the commercial production method due to the reduction of the yield, the production of the target compound of low purity and the increase of the production cost.
<화학식Ⅲ><Formula III>
뿐만 아니라, 대한민국 공개특허 제2003-0058934호에 제시되어 있는 방법으로 진행하기 위해서는 출발물질의 수급에 제한이 많고 특히 상기 방법에서 출발물질로 사용하고 있는 3-(4-나이트로페닐)프로필브로마이드 화합물의 경우 상업적으로 수급에 어려움이 있어 상대적으로 가격이 높기 때문에 결국은 목적하는 화합물에 대한 제조 원가의 상승부분으로 작용하여 산업화에 적용하기 위한 제조 방법을 개발하는 데에 더욱 불리한 요소가 될 수밖에 없다. In addition, in order to proceed with the method disclosed in Korean Patent Laid-Open Publication No. 2003-0058934, there are many restrictions on supply and demand of starting materials, and in particular, 3- (4-nitrophenyl) propyl bromide compound used as starting material in the above method. In the case of the commercial supply and demand is difficult because of the relatively high price in the end will act as a rising part of the manufacturing cost for the desired compound will be further disadvantageous to develop a manufacturing method for applying to industrialization.
이에 본 발명자들은 생산의 용이성과 화학식Ⅲ에서 제시된 모노머(monomer) 생성 문제를 원천적으로 해결하기 위하여 본 발명자들이 연구를 한 결과, 알킬 5-(치환된 페닐알킬)아미노살리실레이트(alkyl 5-(substituted phenylalkyl)amino salicylate)를 중간체로 사용하여 제조함으로써 고 순도 및 고 수율의 목적 화합물을 얻을 수 있음을 확인하고 발명을 완성하였다.Therefore, the inventors of the present inventors have conducted research to solve the problem of the production of monomer and the monomer production presented in the formula (III). As a result, the alkyl 5- (substituted phenylalkyl) aminosalicylate (alkyl 5- ( By using substituted phenylalkyl) amino salicylate) as an intermediate, it was confirmed that the target compound of high purity and high yield was obtained, and the invention was completed.
본 발명의 목적은 불순물로 작용하던 상기 화학식Ⅲ의 모노머(monomer) 생성을 원천적으로 방지한 5-(치환된 페닐알킬)아미노살리실산(5-(substituted phenylalkyl)amino salicylic acid)의 신규 제조방법을 제공하여 상업적 규모로 생산이 가능하고 고 순도 및 고 수율로 목적 화합물을 얻을 수 있는 제조방법을 제공하는데 그 목적이 있다. SUMMARY OF THE INVENTION An object of the present invention is to provide a novel method for preparing 5- (substituted phenylalkyl) amino salicylic acid, which originally prevented the formation of the monomer of Formula III, which acted as an impurity.

상기한 바와 같이, 본 발명은 5-(치환된 페닐알킬)아미노살리실산(5-(substituted phenylalkyl)amino salicylic acid)화합물의 제조에 관한 것으로 5-(치환된 페닐알킬)아미노살리실산(5-(substituted phenylalkyl)amino salicylate) 유도체를 핵심 중간체로 사용하는 새로운 제조공정으로서, 기존의 대한민국 공개특허 제 2003-0058934호를 이용하는 방법은 반응 중에 모노머가 생성되어 이로 인하여 중합반응이 일어나고 그 때문에 반응성이 떨어지고, 그로 인한 반응시간도 오래 지속 되며, 수율이 낮고, 정제의 많은 어려움이 있다. 또한 정제에 드는 비용이 많이 소요되어, 이로 인한 생산단가가 높아지는 문제점을 갖고 있는 반면, 본 발명에서는 반응식 II의 [경로 1], [경로 2], [경로 3]을 통하여 공정이 간단하고 선행기 술 방법에서 발생 될 수 있는 모노머(monomer) 생성을 근원적으로 방지하여 저 비용 및 고 수율로 목적 화합물을 화학식 I을 간편하게 얻을 수 있고, 이러한 화학식 I은 급성 및 퇴행성 뇌신경계 질환의 예방 및 치료제로 이용 가능하며, 알츠하이머병, 파킨슨씨병 및 헌팅턴씨병 등의 퇴행성 뇌신경계 질환, 간질 등의 경련성 뇌신경계 질환 및 뇌졸중 등의 허혈성 뇌신경계 질환의 예방 및 치료 등에도 유효하게 이용될 수 있다.As described above, the present invention relates to the preparation of 5- (substituted phenylalkyl) amino salicylic acid compounds, and 5- (substituted phenylalkyl) aminosalicylic acid (5- (substituted) As a new manufacturing process using a phenylalkyl) amino salicylate) derivative as a key intermediate, the existing method using the Republic of Korea Patent Publication No. 2003-0058934 is that monomers are generated during the reaction, thereby causing a polymerization reaction, thereby reducing the reactivity, Due to the long reaction time, the yield is low, there are many difficulties in purification. In addition, the cost of purification is high, and thus, the production cost thereof is increased, whereas in the present invention, the process is simple and precedent through [path 1], [path 2], and [path 3] of Scheme II. It is possible to easily obtain the target compound of formula I at low cost and high yield by fundamentally preventing the production of monomers that may occur in the method of alcohol, which is used as a preventive and therapeutic agent for acute and degenerative neurological diseases. It can be used effectively for the prevention and treatment of degenerative brain neurological diseases such as Alzheimer's disease, Parkinson's disease and Huntington's disease, convulsive neurological system diseases such as epilepsy and ischemic cerebral nervous system diseases such as stroke.
