Reaction Steps

A solution of 3-(4-benzyloxy-3-nitrophenyl)-2-ethoxypropanenitrile (0.54 g, 1.7 mmol) in ethanol (25 ml) and acetic acid (75 ml) containing 10% palladium on carbon (0.40 g) was hydrogenated at 45 psi for 1 hour. The catalyst was filtered and the solution concentrated. The residue was treated with 5% sodium bicarbonate (100 ml) and extracted with ethyl acetate (3×100 ml). The combined extracts were washed with water (2×100 ml) and brine (100 ml), dried over sodium sulfate and concentrated. The product was isolated by column chromatography (silica gel, 2% methanol in chloroform) as a solid (0.20 g, m.p. 114°-115° C.)
