Reaction Steps

To a solution of (3-methoxy-4-nitrophenyl)(dimethyl)phosphane oxide (0.1 g, 0.44 mmol) in 5 mL of EtOH was added 10% weight of palladium on carbon (0.2 g). The mixture was purged with argon, and hydrogenated under 30 psi for 2 h. The mixture was passed through Celite to a flask containing HCl in ethanol. Concentration of the filtrate gave the final product (0.088 g, 86% yield). MS/ES+: m/z=199.
