実験手順

To a suspension of 3-(hydroxymethyl)pyrido[2,3-e]pyrrolo[1,2-c]pyrimidin-6(5H)-one (50.00 mg, 0.232 mmol), 3-fluoro-N-methyl-4-(piperazin-1-yl)benzamide (68.9 mg, 0.290 mmol) and (cyanomethyl)trimethylphosphonium iodide (90 mg, 0.372 mmol) in Propiononitrile (Volume: 1.00 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.202 mL, 1.162 mmol) at 23° C. The reaction was stirred at 95° C. for 15 hr. The suspension was cooled to 23° C., concentrated via rotary evaporation, re-constituted in ACN (2.0 mL), stirred for 15 min, filtered, rinsed with ACN (3×1 mL) and dried in vacuo. The crude solid was re-suspended in ACN (2.0 mL), heated to reflux, cooled to 23° C., filtered, rinsed with ACN (3×2.0 mL) to provide 3-fluoro-N-methyl-4-(4-((6-oxo-5,6-dihydropyrido[2,3-e]pyrrolo[1,2-c]pyrimidin-3-yl)methyl)piperazin-1-yl)benzamide (0.081 g, 0.186 mmol, 80.0% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.54-2.63 (m, 4H) 2.75 (d, J=4.55 Hz, 3 H) 3.08-3.17 (m, 4 H) 3.63 (s, 2 H) 6.71-6.75 (m, 1 H) 7.02-7.10 (m, 2 H) 7.53-7.63 (m, 3 H) 7.67 (dd, J=3.03, 1.52 Hz, 1 H) 8.29 (q, J=4.29 Hz, 1 H) 8.33-8.38 (m, 1 H) 11.56 (br. s., 1 H).
