Reaction Steps

Solid pyridin-3-amine (156 mg, 1.66 mmol) was added in one charge to a stirred solution of 5-bromo-2-({[2-(methyloxy)phenyl]methyl}oxy)benzoic acid (may be prepared as described in Description 32; 280 mg, 0.83 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (191 mg, 1.00 mmol) and 1-Hydroxybenzotriazole (135 mg, 1.00 mmol) in DMF (20 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=2:1) to yield the title compound as a white solid. 270 mg.
