Reaction Steps

Ms-CI (0.023 ml, 0.30 mmol) was added to a solution of 4-bromo-N-({4-chloro-3-[(3-chloro-5-cyanophenyl)oxy]-2-fluorophenyl}methyl)-2-(hydroxymethyl)-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (0.097 g, 0.15 mmol) and DIEA (0.26 ml, 1.50 mmol) in DMF (1 ml) and the reaction mixture was stirred at room temperature for 1 h. Ammonia (1 ml of a 7M solution in methanol, 7.00 mmol) was added and stirring was continued overnight. Deprotection using similar procedures as that described herein and purification by Reverse-Phase HPLC (water:acetonitrile with 0.1% NH4OH) provided the title compound (0.004 g, 5%) as an off-white solid. 1H NMR (400 MHz, METHANOL-d4) δ ppm 8.32 (br. s., 1H), 7.56 (s, 1H), 7.33-7.45 (m, 2H), 7.28 (br. s., 1H), 7.21 (s, 1H), 4.65 (br. s., 2H), 4.19 (s, 2H). ES-LCMS: m/z 511.9, 513.9, 515.9 (M+1).
