実験手順

A mixture of (6-benzyloxy-1H-indol-3-ylmethyl)-trimethylammonium iodide (2.2 g, 5 mmol), sodium cyanide (500 mg, 10.2 mmol), and 95% EtOH (50 mL) was refluxed under nitrogen for 5 hours. The solvent was removed in vacuo, and the residue was taken in DCM, and washed with water, then dried with sodium sulfate, and evaporated in vacuo to afford a white solid, which was recrystallized from EtOH to give (6-benzyloxy-1H-indol-3-yl)-acetonitrile (1.25 g, 86%). MS (ES): 263 (MH+).
