A mixture of 1-(4-nitrobenzyl)phosphorinane-1-oxide (2.25 g) and 10% Pd—C (0.2 g) in ethanol (30 ml) was vigorously stirred under hydrogen atmosphere for 24 hours. The catalyst was filtered off, and the filtrate was concentrated recrystallized from ethanol-diethylether to give 1-(4-aminobenzyl)-phosphorinane-1-oxide (1.5 g) as pale yellow crystals.
