In a sealed tube, 2- (2, 8-dimethylimidazo [1 ,2-b]pyridazin-6-yl)-7-fluoro-9-methyl- pyrido[1,2-a]pyrimidin-4-one (Intermediate 4; 50 mg, 0.155 mmol) and (S)-2-methylpiperazine (62 mg, 0.6 19 mmol, 4.0 eq.) were stuffed in DMSO (2 mL) at 125C overnight. The solvent was removed under high vacuum. The residue was taken up in CH2C12 and washed with an aqueoussaturated solution of NaHCO3. The organic layer was separated and dried over Na2SO4 and concentrated in vacuo. The crude was purified by column chromatography (Si02, CH2C12/MeOH=95/5 to 90/10) to afford the title product (45 mg, 72%) as a light yellow solid. MS m/z 404.3 [M+Hi., 74879-18-8
