Reaction Steps
A mixture of 4-nitrobenzyldipropylphosphine oxide (3.0 g) and 5% Pd-C (0.3 g) in ethanol (50 ml) was vigorously stirred under hydrogen atmosphere for 16 hours, and the Pd-C was filtered off. The filtrate was concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethanol/ethyl acetate=1:5→1:4) and recrystallized from ethanol-ethyl acetate to give 4-aminobenzyldipropylphosphine oxide (1.78 g) as colorless crystals.
