Procedure

To a solution of cis-3-benzyl-6-(2,4-dichloro-phenyl)-8-methyl-2,3,4,4a,9,9a-hexahydro-1H-3-aza-fluorene (85 mg, 0.20 mmol) in MeOH (3.0 mL) was added Pd(OH)2 (17 mg, 20 wt %) and catalytic amount of acetic acid. The reaction mixture was stirred at 20° C. for 3 days under H2 atmosphere, filtered through celite and concentrated in vacuo. The residue was chromatographed in silica gel column (Hex/EtOAc 1/1) to give the title compound (22 mg, 0.084 mmol): MS (ES) 264.2 (M+H).
