Acetic Anhydride → N-(2,3-dichlorophenyl)acetamide

Participants

Reaction Steps

To a solution 2.06 g (12.71 mmol) of 2,3-dichloroaniline (16-1) in 10 mL of benzene cooled in an ice bath was added drop wise a 10 mL benzene solution of 1.95 g (19.07 mmol) of acetic anhydride. The reaction mixture was then brought to reflux for 1 hour, cooled to room temperature and filtered off the desired product 16-2. MS (M+1): theoretical 203.0; measured 204.1. 1H NMR (CDCl3): 2.26 (s, 3H), 7.21 (m, 2H), 7.68 (m, 1H), 8.33 (m, 1H).
