Reaction Steps

To a suspension of 2-chloro-9-methoxy-6,7-dihydro-pyrimido[6,1-a]isoquinolin-4-one (6) (919 mg, 3.5 mmol) in NH3/EtOH (7 mL) was stirred in an autoclave at 120° C. overnight. After cooling, the precipitate was filtered and washed with MeOH to give the title compound (898.3 mg, quant.). 1H-NMR (400 MHz, d6-DMSO) δ 7.99 (b, 1H), 7.71 (d, 1H), 7.44 (b, 1H), 7.01 (dd, 1H), 7.00 (s, 1H), 6.22 (s, 1H), 3.95 (t, 2H), 3.85 (s, 3H) and 2.97 (t, 2H); MS (ESI) (M+H)+ 243.
