Thereafter, 2-chloro-4-nitrobenzoyl chloride (450 g, 2.1 m) was added dropwise to a stirred 28% ammonia solution (2,000 ml) at below room temperature between 9° and 16° C. The precipitated reaction mixture was washed with water and 30% methanol and then vacuum-dried to yield 2-chloro-4-nitrobenzamide (379 g, 90%, mp 168°-170° C.).
