Procedure
To a suspension of sodium hydride (60%, 0.12 g) in diethyl ether (5 mL) were added a solution of 4-(tert-butyldiphenylsilanyloxy)-buta-2-ennitrile (0.81 g) and p-toluensulfonylmethylisocyanide (0.49 g) in diethyl ether (5 mL) and dimethylsulfoxide (5 mL). After stirring at room temperature for 5 hours, to this reaction mixture was added water and this reaction mixture was extracted with ethyl acetate. This organic layer was washed with brine, dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=60/40-39/61) to give the title compound (0.50 g).
