4-(tert-Butyl-dimethyl-silanyloxymethyl)-1-(4-fluoro-phenyl)-1H-imidazole is dissolved in THF and cooled to −78° C. n-Butyl lithium in hexane is added dropwise. The reaction mixture is warmed up to −25° C., kept at −25° C. for 10 min and then cooled again to −78° C. Iodomethane is added dropwise. The reaction mixture is slowly warmed up to room temperature and stirred at room temperature overnight. The desired compound 4-(tert-butyl-dimethyl-silanyloxymethyl)-1-(4-fluoro-phenyl)-2-methyl-1H-imidazole is obtained.
