Reaction Steps

0.28 g of (±)-trans-6-ethyl-8a-(3-methoxyphenyl)-3-methyl-2-phenylaminocarbonyl-4,4a,5,6,7,8,8a,9-octahydro-1H-pyrrolo[2,3-g]isoquinoline were treated with 0.35 (1.9 mmol) of boron tribromide as described in example 2. The residue was purified by flash chromatography (EtOAc/MeOH/conc. NH4OH 80:20:2) yielding 0.06 g of the title compound. M.p.=271°-272° C.
