Procedure
To a suspension of 3-amino-1-(tert-butyldiphenylsilyloxymethyl)-2,6-dimethylbenzene (42.4 g) in pyridine (17.2 g) and N,N-dimethylformamide (212 ml) was added phthalimidoacetyl chloride (25.6 g) over the period of 15 minutes under ice-cooling, and the mixture was stirred for 1 hour at the same temperature. Water was added thereto, and the resulting precipitate was collected by filtration and washed with acetone to give 1-(tert-butyldiphenylsilyloxymethyl)-2,6-dimethyl-3-(phthalimidoacetylamino)benzene (59.1 g) as colorless crystals.
