Water → N-[(2-chlorophenyl)methyl]acetamide

Participants

Reaction Steps

42.8 kg (0.3 kmoles) of (2-chlorophenyl)methylamine was dissolved in 118.3 kg of dichloromethane and 32.2 kg (0.315 kmoles) of acetic anhydride was added dropwise at 20 to 40° C. over 1.5 hours, followed by aging at room temperature for 30 minutes. After the completion of the reaction, 60 kg of water was added 55.2 kg of an aqueous 25% sodium hydroxide solution was added dropwise at 20 to 40° C. over 20 minutes. The organic layer was partitioned to obtain 169.9 kg of a dichloromethane solution of N-[(2-chlorophenyl)methyl]acetamide.
