Participants

Reaction Steps

To a solution of N-({3-[(2-amino-5-cyano-4-fluorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (110 mg, 0.194 mmol) in Acetonitrile (8 ml) was added tert butyl nitrite (0.046 ml, 0.387 mmol) and the reaction mixture was stirred at RT for 1 hour. The reaction mixture was diluted with EtOAc and washed with water. The solvent was removed and the crude material was purified via silica gel chromatography to give 4-chloro-N-({4-chloro-3-[(3-cyano-4-fluorophenyl)oxy]-2-fluorophenyl}methyl)-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (49 mg, 0.089 mmol, 46% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.76 (t, 1H), 7.98 (s, 1H), 7.42-7.59 (m, 3H), 7.29-7.42 (m, 2H), 5.49 (s, 2H), 4.48 (d, 2H), 3.38 (t, 2H), 0.75 (t, 2 H), −0.09 (s, 9H).
