実験手順
The procedure of Preparation Example 7 was repeated, except that 2.058 g of 4-(tert-butyldimethylsilyloxy)benzyl chloride was used in place of 4-benzyloxybenzyl chloride, and 0.946 g of 4-aminobenzonitrile was used in place of 4-aminophenol. The resulting crude product was purified by silica gel column chromatography (using a 3:1 mixture of hexane and ethyl acetate as the eluent) to obtain 0.682 g of 4-[N-(4-tert-butyldimethylsilyloxybenzyl)amino]benzonitrile.
