이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
종래 방법은 화학식 (1)의 화합물을 용매인 물에 도입시키고 염기인 트리에틸아민을 적가하여 완전히 맑은 용액을 만든 후, 화학식 (2)의 화합물을 반응용액에 넣은 후 반응이 완료되면 여과를 수행하였다.In the conventional method, a compound of formula (1) is introduced into water as a solvent, triethylamine as a base is added dropwise to form a completely clear solution, and then the compound of formula (2) is added to a reaction solution and then filtered when the reaction is completed. It was.
본 발명에서는 하기 반응식 (1)과 같이, 계면활성제를 사용함으로써 여과시간을 종래방법에 비해 5 내지 20 배, 바람직하게는 15 내지 20 배 단축시키고, 또한 반응온도를 상승시켜 반응시간을 8 내지 10시간에서 2 내지 3시간으로 단축시킴으로써 상업생산에 경제적으로 매우 중요한 회전시간(Cycle Time)을 획기적으로 단축할 수 있는 방법을 제공한다. 본 발명에서 바람직한 계면활성제는 메톨로즈(하이드록시프로필 메틸셀룰로스 또는 메틸셀룰로스; USP)이다.In the present invention, as shown in the following reaction formula (1), by using the surfactant, the filtration time is shortened by 5 to 20 times, preferably 15 to 20 times, compared with the conventional method, and the reaction temperature is increased to increase the reaction time by 8 to 10 times. By shortening the time from 2 to 3 hours, it provides a way to drastically shorten the cycle time which is economically important for commercial production. Preferred surfactants in the present invention are metolose (hydroxypropyl methylcellulose or methylcellulose; USP).
본 반응에서의 계면활성제의 양 및 종류 그리고 반응온도, 반응순서 등을 포함한 반응조건은 다음과 같다.The reaction conditions, including the amount and type of surfactant in the reaction and the reaction temperature, reaction sequence, are as follows.
일반적으로 계면활성제의 양은 출발물질인 화학식 (1)의 화합물에 대해 0.5 내지 3.0 중량%로 사용될 수 있다. 계면활성제의 사용량이 상기 범위를 벗어나는 경우에는 여과성이 좋지 않은 단점이 있다.Generally, the amount of surfactant can be used at 0.5 to 3.0% by weight relative to the compound of formula (1) as starting material. When the amount of the surfactant is out of the above range, there is a disadvantage in that the filterability is not good.
또한, 계면활성제는 셀룰로스 에테르(Cellulose Ether) 계통의 계면활성제인 메톨로즈를 사용함으로써 가장 좋은 결과를 얻을 수 있다. 특히, 상온반응의 경우 메톨로즈중의 하나인 메틸셀룰로스, SM-25 를 사용할 때 가장 좋은 결과를 얻었으며(대략 10배의 여과시간 단축), 40℃ 반응의 경우 메틸로즈중의 하나인 하이드록시프로필 메틸셀룰로스 2910, 60SH-50 을 사용했을 때 가장 좋은 결과를 얻을 수 있었다(15 내지 20배의 여과시간 단축).In addition, the surfactant can be obtained the best results by using the Metolose, a surfactant of the cellulose ether (Cellulose Ether) system. In particular, the room temperature reaction showed the best results when using methylcellulose, SM-25, which is one of metolose (approximately 10 times less filtration time), and hydroxy, which is one of methylose, at 40 ° C. The best results were obtained when propyl methylcellulose 2910, 60SH-50 was used (15-20 times less filtration time).
반응온도는 0℃ 내지 40℃ 가 가능하며, 반응온도에 따라 적절한 계면활성제를 선택하여 첨가한다. 예를 들어, 상기와 같이 상온반응의 경우에는 메틸셀룰로스, SM-25를 사용하고, 40℃ 반응의 경우에는 하이드록시프로필 메틸셀룰로스 2910, 60SH-50를 사용한다.The reaction temperature may be 0 ° C to 40 ° C, and an appropriate surfactant is selected and added according to the reaction temperature. For example, in the case of the room temperature reaction as described above, methyl cellulose, SM-25 is used, and in the case of the 40 ℃ reaction hydroxypropyl methyl cellulose 2910, 60SH-50 is used.

Thereafter, after the addition of the surfactant, the reaction temperature is optionally increased, and the reaction is completed by adding the compound of formula (2) or a salt thereof and completing the reaction.
둘째, 화학식 (1)의 화합물 또는 그의 염과 계면활성제를 함께 용매에 넣은 후 염기를 넣고, 경우에 따라 반응온도를 높인다. 이때, 경우에 따라 염기는 대략 2 시간에 걸쳐 첨천히 첨가할 수 있다. 그후, 화학식 (2)의 화합물 또는 그의 염을 넣은 후, 필요에 따라 상온에서 2 내지 3시간 정도 반응용액을 숙성시킨다. 반응이 완료되면 여과를 수행한다.Second, the compound of formula (1) or a salt thereof and a surfactant are put together in a solvent, and then a base is added, and if necessary, the reaction temperature is increased. At this time, base may optionally be added over approximately 2 hours. Thereafter, the compound of formula (2) or a salt thereof is added thereto, and then the reaction solution is aged at room temperature for 2 to 3 hours as necessary. Filtration is carried out when the reaction is complete.
본 발명에 따른 방법에서 용매로는 물이 사용되며, 염기로는 트리에틸아민이 사용된다.In the process according to the invention water is used as solvent and triethylamine is used as base.

실시예 3과 동일한 방법으로 실험을 수행하되 염기인 트리에틸아민을 2시간 가량 천천히 적가하여 표제화합물을 고체로 34.52g(잔류용매 6.4%, 수율 78%) 수득하였다. 이때 여과시간은 처음 여과가 3 분, 두 번째 여과 3 분, 마지막 여과가 3분 걸림으로써 비교예 1에 비해 15배 가량 빨라지는 결과를 얻었다.The experiment was carried out in the same manner as in Example 3, except that the base triethylamine was slowly added dropwise for about 2 hours to obtain 34.52 g of the title compound as a solid (6.4% residual solvent, 78% yield). In this case, the filtration time was about 15 times faster than Comparative Example 1 by taking 3 minutes of the first filtration, 3 minutes of the second filtration, and 3 minutes of the last filtration.
실시예 5: 40℃ 반응에서 계면활성제를 염기보다 먼저 넣고 상온에서 반응용액을 2∼3시간 숙성 시킨 예Example 5 Example in which the surfactant was added before the base in the reaction at 40 ° C. and the reaction solution was aged at room temperature for 2 to 3 hours
7-(4-아미노메틸-3-메톡시이미노피롤리딘-1-일)-1-사이클로프로필-6-플루오로-4-옥소-1,4-디하이드로[1,8]나프티리딘-3-카르복실산의 제조7- (4-aminomethyl-3-methoxyiminopyrrolidin-1-yl) -1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro [1,8] naphthyridine- Preparation of 3-carboxylic Acid
실시예 3과 동일한 방법으로 실험을 수행하되 반응이 끝난 용액을 상온에서 2∼3시간 숙성시킨 후 표제화합물을 고체로 33.23g(잔류용매 6.5%, 수율 75%) 수득하였다. 이때 여과시간은 처음 여과가 3 분, 두 번째 여과 2 분, 마지막 여과가 2분 걸림으로써 비교예 1에 비해 20배 가량 빨라지는 결과를 얻었다.The experiment was carried out in the same manner as in Example 3, but the resultant solution was aged at room temperature for 2 to 3 hours to obtain 33.23 g of the title compound as a solid (6.5% residual solvent, 75% yield). In this case, the filtration time of the first filtration was 3 minutes, the second filtration 2 minutes, the last filtration took 2 minutes, the result was about 20 times faster than Comparative Example 1.
