0.63 g (1.37 mmol) of (±)-trans-6-ethyl-8a-(3-methoxyphenyl)-3-methyl-2-pyrrolidinocarbonyl-4,4a,5,6,7,8,8a,9-octahydro-1H-pyrrolo[2,3-g]isoquinoline were treated with 0.77 ml (8.22 mmol) of boron tribromide as described in example 2. The residue was purified by flash chromatography (EtOAc/MeOH/conc. NH4OH 80:20:0.5). The resulting solid was triturated with Et2O, yielding 0.13 g of the title compound. M.p.=224°-226° C.
