실험 절차

To 3-cyclopropylmethoxy-4-difluoromethoxybenzyl chloride (26 g) in dimethylformamide (150 mL) under an argon atmosphere was added sodium cyanide (9.7 g, 198 mmol). The resulting mixture was stirred at room temperature and heated gently for 2 h, then cooled and concentrated. The mixture was partitioned between basic brine and ether and extracted twice. The organic extract was washed with brine and was dried (sodium sulfate). The solvent was removed in vacuo to provide an orange-brown oil (24 g), which was used without purification.
