実験手順

Solid pyridin-3-amine (99 mg, 1.05 mmol) was added in one charge to a stirred solution of 5-bromo-2-(4-chlorobenzyloxy)benzoic acid (may be prepared as described in Description 16, 180 mg, 0.53 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (121 mg, 0.63 mmol) and 1-Hydroxybenzotriazole (85 mg, 0.63 mmol) in DMF (15 ml) under nitrogen at 20° C. The reaction mixture was stirred at 20° C. for 16 h. The organic phase was washed with water (25 ml), extracted with ethyl acetate (3×30 ml), dried over sodium sulphate, evaporated in vacuo and purified by column chromatography (petroleum ether:ethyl acetate=1.5:1) to yield the title compound as a white solid. 200 mg.
