Reaction Steps

A solution of 2,3-dichloroaniline (5.00 g, 30.86 mmol) in pyridine (20 ml) was cooled to 0° C. and treated with AcCl (4.85 g, 62 mmol). The reaction mixture was stirred at r.t. for 1 h and then concentrated under reduced pressure. The residue was dissolved in ethyl acetate, washed with 1% aqueous hydrochloric acid, water and brine, and dried over MgSO4. The solution was concentrated and recrystallized from EtOAc/hexane to give (2,3-dichloro-phenyl)-acetamide (4.50 g, 22 mmol). HPLC Rt: 5.52 min. 1H-NMR (CDCl3): δ 8.35 (br. s, 1H), 7.7 (1H), 7.24 (1H), 7.23 (1H), 2.28 (s, 3H).
