実験手順: A mixture of 4-[(dimethylamino)methyl]-4-piperidinol (1.0 g, 4.33 mmol), 6-amino-4-fluoronicotinonitrile (intermediate 21, 593 mg, 4.33 mmol) and triethylamine (3.62 ml, 26.00 mmol) was heated at 80° C. in a septum sealed reaction vessel under argon for 28 h. The reaction mixture was cooled, EtOH (5 ml) added and heated at 80° C. for 18 h. The reaction mixture was then evaporated, partitioned between aqueous NaHCO3 solution and DCM, extracted 5× with DCM containing 10% MeOH, the combined DCM layers dried over MgSO4 and evaporated. The residue was triturated with Et2O (20 ml) and DCM (1 ml) to give the title compound as a beige solid. 1H NMR (400 MHz, CDCl3) δ 8.15 (s, 1H), 5.82 (s, 1H), 4.70 (s, br, 2H), 3.65-3.58 (m, 2H), 3.27-3.20 (m, 2H), 2.38 (s, 6H), 2.26 (s, 2H), 1.68-1.62 (m, 4H).
