Procedure

A mixture of 4-bromo-3-methylbenzoic acid (430 mg), N,N-dimethylethylenediamine (180 mg), 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide hydrochloride (600 mg) and 4-dimethylaminopyridine (244 mg) in dichloromethane (20 mL) was stirred at ambient temperature for 4 hours, diluted with ethyl acetate (200 mL), washed with water and brine, and dried (Na2SO4), filtered and concentrated. The concentrate was purified by flash column chromatography with 10% ethyl acetate in ammonia saturated dichloromethane.
