Procedure
A mixture of (S)—N-{1-[3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl]propan-2-yl}-1H-imidazole-4-carboxamide (120 mg, 0.338 mmol), 2-(chloromethyl)-2-methyloxirane (2.88 g, 27.1 mmol and Y(NO3)3×6H2O (3.6 mg, 0.0093 mmol) was stirred under MW at 120° C. for 30 min. After evaporation of oxirane the residue was purified by flash chromatography on silica gel using CH2Cl2-MeOH as a gradient eluent (100:0-99:1) to obtain N-{(S)-1-[3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl]propan-2-yl}-1-[(2-methyloxiran-2-yl)methyl]-1H-imidazole-4-carboxamide as a major product and 1-(3-chloro-2-hydroxy-2-methylpropyl)-N—{(S)-1-[3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl]propan-2-yl}-1H-imidazole-4-carboxamide as a minor product.
