In a sealed tube, 7-fluoro-2-(2-methylimidazo[1,2-b]pyridazin-6-yl)-4H-pyrido[1,2-a]pyrimidin-4-one (Intermediate 1; 50 mg, 0.169 mmol), and (R)-2-methylpiperazine (68 mg, 0.677 mmol, 4.0 eq.) were stirred in DMSO (2 mL) at 110 C. overnight. The solvent was removed under high vacuum. The residue was taken up in CH2Cl2 and washed with an aqueous saturated solution of NaHCO3. The organic layer was separated and dried over Na2SO4 and concentrated in vacuo. The crude was purified by column chromatography (SiO2, CH2Cl2/MeOH=95/5 to 90/10) to afford the title product (48 mg, 75%) as a light yellow solid. MS m/z 376.3 [M+H+].
