실험 절차

(R)-3-(hydroxymethyl)-6a,7,9,10-tetrahydropyrido[3,2-e][1,4]thiazino[4,3-a]pyrazin-6(5H)-one (80.0 mg, 0.318 mmol) was suspended in propionitrile (0.8 mL) and (cyanomethyl)trimethylphosphonium iodide (93.0 mg, 0.382 mmol) was added followed by N-ethyl-N-isopropylpropan-2-amine (167 ul, 0.955 mmol). To the stirred mixture was then added 4-(piperazin-1-yl)benzonitrile (59.6 mg, 0.318 mmol). The reaction was heated to 90° C. with stirring for 16 h. The reaction was cooled to room temperature and left to sit 48 h. The precipitate was filtered off, washed with ethanol (5 mL) and dried in vacuum to afford the title compound (36.0 mg, 26.9%) as a white solid. 1H NMR (CHLOROFORM-d) δ (ppm): 8.26 (br. s., 1H), 7.79 (d, J=1.8 Hz, 1H), 7.44-7.60 (m, 2H), 6.96 (br. s., 1H), 6.76-6.91 (m, 2H), 5.05 (dt, J=13.6, 2.7 Hz, 1H), 4.43 (dd, J=10.7, 3.2 Hz, 1H), 3.27-3.63 (m, 6H), 3.15 (td, J=12.8, 2.3 Hz, 1H), 3.00 (td, J=12.8, 2.7 Hz, 1H), 2.77-2.93 (m, 2H), 2.59 (br. s., 4H), 2.34-2.45 (m, 1H). [M+H] calc'd for C22H24N6OS, 421; found, 421.
