実験手順
A mixture of 4-hydroxy-2,6-dimethyl-benzaldehyde (150 mg), chloroacetonitrile (0.1 mL), and Cs2CO3 (390 mg) in acetone (10 mL) was stirred at room temperature for 16 h. The mixture was concentrated, diluted with water, and extracted with EtOAc. The organic extracts were washed with brine, dried over Na2SO4, and concentrated in vacuo. Purification by column chromatography (SiO2, 3:1 hexane/EtOAc) gave (4-formyl-3,5-dimethyl-phenoxy)-acetonitrile.
