Reaction Steps

Solid pyridin-3-amine (91 mg, 0.96 mmol) was added in one charge to a stirred solution of 5-bromo-2-{[(2-cyanophenyl)methyl]oxy}benzoic acid (may be prepared as described in Description 34; 160 mg, 0.48 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (111 mg, 0.58 mmol) and 1-Hydroxybenzotriazole (78 mg, 0.58 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), and 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. 180 mg.
