Reaction Steps

A mixture of 5-acetyl-2,3-dihydrobenzo[b]furan, oxime, (Preparation 3, 2.7 g, 16 mmole) in methanol (50 mL), ammonium hydroxide (5 mL) and Raney nickel (3 mL) was hydrogenated on a Parr hydrogenator (H2, 50 psi) for 2 days. The reaction mixture was filtered through Celite and the resultant filtrate was concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using methanol (100%) to give the title compound (1.74 g, 70%) as a brown oil.
