Abstract
The invention discloses a synthetic method of 3-nitroisonicotinic acid methyl ester, which is characterized by comprising the following steps: 1) Dissolving 2-chloro-5-nitro-4-methylpyridine or 2-chloro-3-nitro-4-methylpyridine in a solvent, then adding a first oxidant, and reacting to obtain 2-chloro-5-nitroisonicotinic acid or 2-chloro-3-nitroisonicotinic acid; 2) Adding 2-chloro-5-nitroisonicotinic acid into a chlorinating agent or adding 2-chloro-3-nitroisonicotinic acid into the chlorinating agent, and reacting with alcohol to obtain corresponding 2-chloro-5-nitroisonicotinic acid ester or 2-chloro-3-nitroisonicotinic acid ester; 3) The 3-nitroisonicotinate is obtained by reacting 2-chloro-5-nitroisonicotinate or 2-chloro-3-nitroisonicotinate with a reducing reagent, and the method has the advantages of mild and safe reaction conditions and high yield and is suitable for industrial large-scale production.
Description
Technical Field
The invention relates to the field of synthesis of medicine and pesticide intermediates, in particular to a synthesis method of 3-nitroisonicotinic acid methyl ester.
Background
In general, aromatic substrates are very inert with respect to nucleophilic substitution. However, compounds having strongly electron-withdrawing groups in the ortho-or para-position, which accelerate the dissociationAnd (4) removing. The nitro group, which is not normally lost in aliphatic systems, is a particularly good leaving group in nucleophilic substitution reactions. The nitro group in methyl 3-nitroisonicotinate, since the combination of the pyridyl aromatic system with the stable carbonyl anion to form the ortho group the 3-nitro substituent is a good leaving group. The nitro group in the 3-nitroisonicotinic acid methyl ester can be alkylated in a nucleophilic substitution reaction to generate a new C-C bond and construct more complex carbon skeletons; but also substituted by heteroatoms of oxygen, nitrogen, sulfur and fluoride, yields many new products. Therefore, the 3-nitroisonicotinic acid methyl ester has wide application in organic synthesis. However, few reports on the synthesis of 3-nitromethyl isonicotinate exist, and the prior literature reports that methyl isonicotinate is obtained by nitration with dinitrogen pentoxide, but N is 2 O 5 The pure product is very unstable, is easy to sublimate at room temperature and explodes under the irradiation of sunlight; the crystal has sublimation phenomenon at room temperature, white crystals gradually become light yellow, orange yellow or even tan along with the rise of temperature, the crystal is in liquid state at about 45 ℃ and decomposes to release oxygen, nitrogen dioxide and the like, and if the crystal meets high temperature or flammable substances, the crystal can explode. In view of the danger of dinitrogen pentoxide, the method has the defects that the dinitrogen pentoxide can not be produced in a large scale, can only be used for a small amount of current work in a laboratory, and is easy to cause danger due to high temperature. Therefore, a method for synthesizing 3-nitroisonicotinic acid methyl ester by using dinitrogen pentoxide is avoided, and a new method which is mild and safe in reaction conditions and suitable for industrial large-scale production needs to be found urgently.
