Reaction Steps
A mixture of 4-(3-cyano-4-methoxyphenyl)-N-cyclohexyl-N-methyl-1H-imidazole-1-carboxamide (305 mg, 0.901 mmol), dibutylstannanone (28.0 mg, 0.113 mmol) and azidotrimethylsilane (0.239 ml, 1.803 mmol) was heated in toluene (8 mL) at 115° C. for 20 h. The mixture was then cooled to room temperature and evaporated to dryness. The crude product was chromatographed over silica using a mixture of dichlormethane/methanol (95:5). After evaporation of the homogenous fractions, the residual product was triturated with diethyl ether, filtered and dried to give the product as off-white crystals, (196 mg, 54%).
