Procedure

5.2 g of 4-chloro-3-(2-chloro-2-ethoxycarbonyl-ethenyl)aniline in 30 ml of dichloromethane were added dropwise at 25° C. to a solution of 2.56 g of 3-methylglutaric anhydride in 50 ml of dichloromethane. After 3 h, the deposited precipitate was removed and washed with dichloromethane. Yield: 5 g; m.p.: 137°-138° C.

Workup

  1. customthe deposited precipitate was removed
