Versuchsvorschrift
tert-Butyl 6a-phenyl-3,3a,4,6-tetrahydro-1H-pyrrolo[3,4-c]isoxazole-5-carboxylate (142 mg, 489.04 mmol) is dissolved in methanol (10 mL). The solution is put through a flow hydrogenator with the Raney/Ni catalyst bed at 1 atmosphere H2 pressure and at 20° C., with a flow rate of 1 mL/min. Wash the bed with 10 mL more of MeOH after all the original solution has passed through. Remove the solvent under reduced pressure to obtain the title compound as a clear oil (168 mg, 117%) EI/MS (m/e): 293.3 (M+H).
