実験手順
Sodium hydride 60% dispersion in mineral oil 93.1 mg was added in one portion to a solution of N-[5-[4-(benzyloxy)phenyl]-1-(4-methoxyphenyl)-1H-pyrazol-3-yl]-N′,N′-dimethylurea 1.43 g in DMF 10 ml under ice bath cooling. The reaction mixture was stirred at ambient temperature for 1 hour. MeI 688 mg was added the reaction mixture was stirred at ambient temperature overnight. The mixture was partitioned between ethyl acetate and H2O. The organic layer was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by silica gel column chromatography eluted with AcOEt-n-hexane=75%, 80% to give N-[5-[4-(benzyloxy)phenyl]-1-(4-methoxy-phenyl)-1H-pyrazol-3-yl]-N,N′,N′-trimethylurea 1.45 g as an oil.
