実験手順

To a mixture of N-(3-hydroxymethyl-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-N-[(2S)-3-phenoxy-2-(triethylsilyl-oxy)propyl]-tert-butoxycarbonylamine (1.93 g) and triethylamine (0.58 ml) in dichloromethane (40 ml) was added dropwise methanesulfonyl chloride (0.27 ml) under ice-cooling. After stirring at room temperature for 6 hours, the reaction mixture was washed successively with water, sodium bicarbonate solution, water and brine. The organic layer was dried over magnesium sulfate and evaporated in vacuo to afford crude N-[(2S)-3-phenoxy-2-(triethylsilyloxy)propyl]-N-(3-methylsulfonyloxymethyl-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl]-tert-butoxycarbonylamine (2.18 g), which was used without purification.
