実験手順

3.38 g of 2-benzyl-4-(tertbutyloxycarbonylaminomethyl)isoindoline was dissolved in 10 ml of chloroform and 1.27 g of sodium carbonate was added to it. To this solution was added dropwise 2.04 g of benzyl chloroformate under ice-cooling and stirring, and the mixture was stirred for 2 hours at room temperature. Insoluble materials were removed by filtration and the filtrate was concentrated. Recrystallization from ether gave 3.48 g of 2-benzyloxycarbonyl-4-(tertbutyloxycarbonylaminomethyl)isoindoline.
