Paragraph 0018; 0022; 0026, (2018/12/14)
The invention discloses a method for synthesizing zuozuo lin grass ester, which belongs to the field of chemical industry. The specific process is as follows: the 2, 6 - diethyl - 4 - methylaniline by thermal decomposition is diazotized with sodium nitrite to generate 2, 6 - diethyl - 4 - methyl bromo; the malonic acid diethyl ester is added to the [1, 4, 5] - oxa diazepine b hydrobromide and alkali catalyst, synthesis of dihydro - 1 H - pyrazolo [1, 2 - d] [1, 4, 5] oxygen mixed two aza - 7, 9 (2 H, 8 H) - dione, it with 2, 6 - diethyl - 4 - methyl bromophenylacetic after coupling reaction to obtain the 8 - (2, 6 - diethyl - 4 - methyl phenyl) and four hydrogen pyrazole [1, 2 - d] [1, 4, 5] oxygen and nitrogen weed - 7, 9 (2 H, 8 H) - dione; will it with new pivaloyl chloride reaction zuozuo lin grass ester synthesis of the final product. This invention shortens the synthesis step, the operation is simple, and the cost is reduced, high economical efficiency and less pollution to the environment. (by machine translation)
