To a solution of 5-nitro-2-chlorobenzoic acid (1 g), 1-hydroxybenzotriazolemonohydrate (1.14 g) and 1-ethyl-3-(3-dimethylaminopyridyl)carbodiimide hydrochloride (1.42 g) in N,N′-dimethylformamide (10 mL) were added dimethylamine hydrochloride (0.61 g) and triethylamine (1 mL). The mixture was stirred for all day and night, and then water was added. The reaction solution was extracted with ethyl acetate, and the extract was washed with saturated aqueous sodium bicarbonate and saturated brine, dried over magnesium sulfate, and concentrated to give the title compound (1.13 g).
