Reaction Steps
To a mixture of 2-(3-amino-phenylamino)-9-methoxy-6,7-dihydro-pyrimido[6,1-a]isoquinolin-4-one (§) (20.0 mg, 0.06 mmol) in THF (2 mL), triethylamine (13 μL, 0.09 mmol) and 3-bromobenzoylchloride (10 μL, 0.07 mmol) was added and stirred at 50° C. for 2 hrs. The mixture was quenched with concentrated HCl and purified on BondElut® SCX (Varian Incorporated). Formed solid was washed with CH2Cl2 to give the title compound (25.3 mg, 81%). 1H-NMR (400 MHz, d6-DMSO) δ 10.43 (s, 1H), 9.68 (s, 1H), 8.15 (t, 1H), 8.08 (s, 1H), 7.97 (dt, 1H), 7.81 (ddd, 1H), 7.75 (brd, 1H), 7.70 (d, 1H), 7.51 (t, 1H), 7.36 (dt, 1H), 7.31 (t, 1H), 7.05-6.98 (2H), 6.42 (s, 1H), 3.99 (t, 2H), 3.84 (s, 3H) and 2.97 (t, 2H); MS (ESI) (M+H)+ 517, 519.
