Reaction Steps
The crude 2-chloro-4-(2'-methylpropionamido)benzoyl chloride from the preceding reaction in dry THF (10 ml) was added dropwise with stirring over 10-15 minutes to a solution of diethylamine (1.46 g) in dry THF (10 ml), at 0°-5° C. After stirring at 0°-10° C. the reaction mixture was stood overnight at room temperature, poured into cold water and extracted with ethyl acetate. This extract was dried and evaporated to give a viscous gum which crystallised slowly and was then recrystallised from ethyl acetate to give 2-chloro-4-(2'-methylpropionamido)-N,N-diethylbenzamide as white crystals (0.507 g).
