Reaction Steps

To a stirred suspension of KCN (18.6 g, 286 mmol) in methanol (100 mL) was added thiophene-3-carbaldehyde (20 mL, 178 mmol) at 0° C. under nitrogen atmosphere. Then acetic acid (4.4 mL) was added dropwise at 0° C. After 30 minutes, the mixture was warmed to 15° C. and stirred for 20 hours. NaHCO3 (15 g) was added. The mixture was concentrated and extracted with ethyl acetate (200 mL). The organic mixture was washed with water (3×25 mL), brine (25 mL), dried over anhydrous sodium sulfate and concentrated to dryness. The residue was purified by column chromatography (ethyl acetate:petroleum ether, 1:10) to afford hydroxy-thiophen-3-yl-acetonitrile. (Yield 15 g, 60%). LC-MS: [M+Na]+ 162.
