PROCEDURE

实验过程

To a mixture of 3-amino-1-(tert-butyldiphenylsilyloxy-methyl)-2,6-dichlorobenzene (348 mg) triethylamine (0.15 ml) and dichloromethane (3.5 ml) was added phthalimidoacetyl chloride (186 mg) under ice-cooling, and the mixture was stirred for 1.5 hours at ambient temperature. Water was added thereto, and the resulting precipitates were collected by vacuum filtration and washed with diisopropyl ether to give 1-(tert-butyldiphenylsilyloxymethyl)-2,6-dichloro-3-(phthalimidoacetylamino)benzene (460 mg) as crystals.
