Reaction Steps

Following the procedure of Example 3, step 4, 0.300 g (1.60 mmol) of crude trans-1,2,3,4,4a,5,6,10b-octahydrobenz[f]isoquinoline in 10 ml of anhydrous DMF was reacted with 0.244 g (1.77 mmol) of anhydrous potassium carbonate and 0.369 g (1.60 mmol) of 4-nitrophenethyl bromide. Chromatography on flash silica, eluting with 50-100% ethyl acetate/petroleum ether, then on a Lobar column, eluting with 50% ethyl acetate/petroleum ether, afforded 0.200 g (37%) of the title product as a white solid. The hydrochloride salt was made using ethereal hydrogen chloride. Upon evaporation of the solvent the title product hydrochloride was obtained as a white solid, m.p. 232°-233° C. (dec).
