To a solution of benzyl 1,4-dioxa-7-azaspiro[4.4]nonane-7-carboxylate (1.1 g) in methanol (30 mL) was added palladium(II) hydroxide (100 mg) at room temperature. The mixture was stirred for 2.5 hr under a hydrogen atmosphere (0.4 MPa). Insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (540 mg) as a dark orange liquid.
