Azane;hydrate → 3-Chloro-4,5-dipropargyloxybenzamide

Participants

Reaction Steps

A solution of 3-choro-4,5-dipropargyloxybenzoyl chloride (1.00 g) in 30% ammonia water (20 ml) and toluene (10 ml) was stirred under reflux for 10 minutes, poured into ice-water and extracted with ethyl acetate. The extract was washed with water, dried over magnesium sulfate and concentrated under reduced pressure to give a residue. The residue was further washed with hexane to give 3-chloro-4,5-dipropargyloxybenzamide (0.88 g). m.p. 122°-125° C.
