実験手順

To a mixture of 30% aqueous KOH (11 mL) and diethyl ether (11 mL) was added N-methyl-N-nitrosourea (0.097 g, 0.938 mmol) in one portion with stirring and cooling at 0° C. and the reaction mixture was maintained at this temperature for 20 min. The organic phase was isolated, dried over KOH pellets and added dropwise to a solution of 4-chloro-N-[(4-chloro-3-{[3-cyano-5-(2-propen-1-yl)phenyl]oxy}-2-fluorophenyl)methyl]-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (0.054 g, 0.094 mmol) and palladium(II) acetate (2.106 mg, 9.38 μmol) in diethyl ether (11.00 mL) with stirring and cooling at 0° C. The reaction mixture was stirred at 0° C. for 1 h and then allowed to warm to room temperature and stirred overnight at which time LC-MS indicated complete conversion to desired product.
