Procedure

66 mg of 8-benzyloxycarbonylamino-1,4-dioxa-spiro[4.6]undecane-8-carboxylic acid methyl ester was dissolved in methanol and hydrogenated in an H-cube™ hydrogenation reactor (ThalesNano, Budapest, Hungary) at a hydrogen pressure of 100 bar at 40° C. over a cartridge with 10% palladium on charcoal. The mixture was evaporated to dryness to yield the crude title compound (32 mg).
