実験手順
A mixture of 1-diphenylmethyl-3-morpholinoazetidine (see PREPARATION 12) (18.6 g, 60.4 mmol), palladium hydroxide (2 g), ethanol (200 ml) and 1N aqueous hydrochloric acid solution (52 ml) was stirred under an atmosphere of hydrogen at 345 kPa (50 p.s.i.) for three days. The catalyst was then removed by filtration and the filtrate evaporated to dryness. Addition of dichloromethane (100 ml) to the residue and trituration yielded a solid which was recrystallised from methanol to give the title compound (10.2 g) as a crystalline solid.
