Reaction Steps

To a mixture of 3-methyl-2,5,7,8,9,10-hexahydro-4H-benzo[g]pyrazolo[4,3-c]quinolin-4-one (1-6) (10.2 g, 40.3 mmol, 1 equiv) and potassium carbonate (30.0 g, 217 mmol, 5.38 equiv) in DMF (100 mL) under nitrogen was added benzyl bromide (35.0 g, 205 mmol, 5.09 equiv) and the resulting mixture was stirred at 23° C. for 16 h. The reaction mixture was filtered and the filtered solid was washed with ether (3×200 mL) followed by water (3×250 mL) and dried to yield 2-benzyl-3-methyl-2,5,7,8,9,10-hexahydro-4H-benzo[g]pyrazolo[4,3-c]quinolin-4-one (1-7) as a white solid. LRMS m/z (M+H) 344.2 found, 344.2 required.
