Benzoyl chloride, 3,4-dichloro- → 3,4-Dichloro-N-(5-chloro-2-hydroxy-4-nitrophenyl)benzamide

Participants

Reaction Steps

3,4-dichlorobenzoyl chloride (2) (38.0 g, 0.18 mol) was added to a stirred slurry of 2-amino-4-chloro-5-nitrophenol (1) (34.0 g, 0.18 mol) in ethyl acetate (250 ml) and the mixture refluxed for 2 h. After cooling the precipitate was filtered and then slurried in hot ethyl acetate (200 ml) and filtered again to give 50 g (77%) 2-(3,4-dichlorobenzamido)-4-chloro-5-nitrophenol (3).
