Participants

Reaction Steps

EDC (0.028 g, 0.148 mmol) and HOBT (0.020 g, 0.148 mmol) were added to a solution of 3-{[3-(aminomethyl)-6-bromo-2-fluorophenyl]oxy}-5-chlorobenzonitrile (0.053 g, 0.148 mmol) and 4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxylic acid (0.041 g, 0.148 mmol) in DMF (2 mL). The mixture was stirred at RT overnight. The reaction mixture was extracted with ethyl acetate and saturated aqueous sodium bicarbonate. The organic layer was dried over sodium sulfate and concentrated to give a yellow oil which was dissolved in dichloromethane (1.5 mL). Trifluoroacetic acid (0.5 ml, 6.49 mmol) was added and the mixture was stirred at RT overnight. Purification by reverse phase HPLC (acetonitrile:water with 0.1% formic acid) gave the title compound 0.002 g, 2.5%) as a white solid. 1H NMR (400 MHz, methanol-d4) δ ppm 7.69 (s, 1H), 7.48-7.55 (m, 2H), 7.29 (t, 1H), 7.22 (d, 1H), 7.19 (s, 1H), 4.61 (s, 2H). ES MS m/z 483 (M+1).
