実験手順
7-(hydroxymethyl)-4-methyl-3,4-dihydropyrido[2,3-b]pyrazin-2(1H)-one (85.0 mg, 0.44 mmol) was suspended in propionitrile (1 mL) and (cyanomethyl)trimethylphosphonium iodide (123.0 mg, 0.51 mmol) was added followed by N-ethyl-N-isopropylpropan-2-amine (180 ul, 1.03 mmol). To the stirred mixture was then added 4-(4-chlorophenyl) piperidine hydrochloride (104.5 mg, 0.45 mmol). The reaction was heated to 90° C. with stirring for 2 h. The reaction was then cooled to room temperature and diluted with water (3 mL) and filtered. The solids were collected and refluxed in ethanol (5 mL) for 1 h. The suspension was cooled back to room temperature and filtered. The precipitate was filtered off and dried in vacuum to afford the title compound (18.1 mg, 11%) as a white solid. 1H NMR (DMSO-d6) δ (ppm): 10.49 (s, 1H), 7.61 (d, J=2.0 Hz, 1H), 7.30-7.36 (m, 2H), 7.23-7.29 (m, 2H), 6.95 (d, J=2.0 Hz, 1H), 3.92 (s, 2H), 3.32 (s, 3H), 2.84-2.92 (m, 5H), 1.98 (t, J=10.7 Hz, 2H), 1.66-1.75 (m, 2H), 1.50-1.64 (m, 2H). [M+H] calc'd for C20H23ClN4O, 371; found, 371.
