-
Paragraph 0041; 0047, (2019/06/13)
The invention discloses a nainai non-west tanzania intermediate 2 - pyrrolidone synthetic method, the 4 - amino - 3 - methyl benzoate with halogenated methane under the effects of catalyst obtained by reaction of 2, 6 - dimethyl aniline, the 4 - amino - 3 - methyl benzoate, protective agent and solvent A reaction mixture obtained from I; halogenated methane, catalyst and solvent B mixing, then mixing the mixture I II into the reaction mixture; adding an aqueous solution of hydrochloric acid in the reaction mixture is mixed with the mixture II III; III will be alkali water dripped into the mixture, the reaction mixture obtained from IV; the mixture is poured into the IV 3 - 4 times of the volume of water, added with a solvent extracting C, layered, organic layer after the water washing, after drying agent, concentrated evaporate the solvent to obtain the product. The method of low cost, high yield, blowdown less.
