To a solution of 3-bromo-4-chlorobenzoic acid (120 mg) in DMF (1 ml) was added a solution of HATU (192 mg) in DMF (1 ml) and a solution of HOBT (69 mg) in DMF (1 ml). To this mixture was added cyclopropylamine (0.04 ml) and DIPEA (0.27 ml). The reaction was stirred at room temperature for 18 hours, before diluting with methanol (5 ml) and filtration through a SPE cartridge (SCX, 2 g). The filtrate was applied to a SPE cartridge (Aminopropyl, 10 g) and washed through with methanol (10 ml). The combined filtrate and washings were reduced to dryness under vacuum to give 3-bromo-4-chloro-N-cyclopropylbenzamide.
