실험 절차

A 250-mL pressure tank reactor was purged, flushed and maintained with a hydrogen atmosphere, then, was added a solution of diethyl (benzylamino)methylphosphonate (3.5 g, 13.62 mmol, 1.00 equiv) in ethanol (180 mL), acetic acid (10 mL) and Palladium carbon (0.2 g, 0.10 equiv). The resulting solution was stirred for 24 h at 50° C. under 20 atm pressure. The solids were filtered out. The resulting mixture was concentrated under vacuum. This resulted in 2.0 g (crude) of the title compound as brown oil which was used without further purification.
