Reaction Steps

A solution of 3-{[3-(aminomethyl)-6-ethyl-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.075 g, 0.246 mmol), 2-azido-4-chloro-1H-imidazole-5-carboxylic acid (0.051 g, 0.271 mmol), EDC (0.052 g, 0.271 mmol) and HOBT (0.041 g, 0.271 mmol) in DMF (4 ml) was stirred at RT under an atmosphere of nitrogen for 16 h then ethyl acetate (100 mL) and saturated aqueous NaHCO3 solution (100 mL) were added. The organic layer was separated, washed with saturated aqueous NaHCO3 solution (100 mL), water (100 mL), dried over MgSO4, filtered and concentrated. Ethyl acetate (20 mL) and Lindlar Catalyst (0.026 g, 0.247 mmol) were added and the mixture was stirred at RT under an atmosphere of hydrogen (55 psig) for 19 h. The vessel was carefully vented and the mixture was filtered thru Celite, concentrated purified by Reverse Phase HPLC (MeCN/water+0.1% TFA) to give the title compound (0.059 g, 51%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.93 (s, 1H), 7.77 (t, 1H), 7.70 (t, 1H), 7.39 (s, 1H), 7.33 (t, 1H), 7.18-7.29 (m, 2H), 5.81 (s, 2H), 4.47 (d, 2H), 2.47-2.54 (m, 2H), 1.08 (t, 3H). LCMS m/z 450.1 (M+H).
