実験手順

To a suspension of 3-formylindole-4-carboxylic acid (390 mg) and potassium carbonate (285 mg) in N,N-dimethylformamide (10 ml) was added benzyl bromide (353 mg) at ambient temperature and the mixture was stirred for 4 hours. The resulting mixture was diluted with ethyl acetate and water, then the layers were separated. The organic layer was washed with brine, dried over magnesium sulfate and concentrated in vacuo. The residual solid was triturated with diethyl ether:n-hexane (1:6) to give benzyl 3-formylindole-4-carboxylate (520 mg).
