Formic Acid → HCID 86640047, compound

Participants

Reaction Steps

A mixture of 5-(5-methyl-1,3,4-oxadiazol-2-yl)-1-benzofuran-3-carbonitrile (1.00 g, 4.44 mmol), Raney-nickel (2.0 g), formic acid (16 mL) and water (4 mL) was heated under reflux for 30 min. After cooling, the reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was diluted with ethyl acetate, washed with water, saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/tetrahydrofuran=1/1) and recrystallized from hexane/tetrahydrofuran to give the title compound (558 mg, yield 55%) as colorless crystals.
