実験手順

To a mixture of methyl 3-(2-hydroxyethylaminomethyl)-5-(pyrrol-1-yl)benzoate (0.8 g) and triethylamine (0.48 ml) was added benzyl chloroformate (0.46 ml) under ice cooling. After stirring for 2 hours under ice cooling, the reaction mixture was poured into the mixture of ethyl acetate and water. The organic layer was washed with brine and dried over magnesium sulfate. The solvent was evaporated in vacuo and the residue was purified by column chromatography on silica gel eluting with the mixture of chloroform and methanol (15:1). The eluted fractions containing the desired product were collected and evaporated in vacuo to give methyl 3-[N-benzyloxycarbonyl-N-(2-hydroxyethyl)aminomethyl]-5-(pyrrol-1-yl)benzoate (1.11 g).
