반응 단계
0.6 g (1.5 mmol) of (±)-trans-6-ethyl-2-ethoxycarbonyl-3-methyl-8a-(3-methoxyphenyl)-4,4a,5,6,7,8,8a,9-octahydro-1H-pyrrolo[2,3-g]isoquinoline were treated with 0.84 ml (9.0 mmol) of boron tribromide as described in example 2. The crude solid was purified by flash chromatography (AcOEt/MeOH/conc. NH4OH 80:20:2), yielding 0.12 g of the title compound. M.p.=195°-197° C.
