YieldReaction ConditionsOperation in experiment
73% With acetic acid; at 110℃;Sealed tube; Example 78 3-(4-Fluorophenyl)-5-(pyridin-3-yl)pyrazolo[1,5-a]pyrimidin-7(4H)-one A solution of 4-(4-fluorophenyl)-1H-pyrazol-5-amine (124 mg, 0.70 mmol, 1.00 equiv) and ethyl 3-oxo-3-(pyridin-3-yl)propanoate (135 mg, 0.70 mmol, 1.00 equiv) in acetic acid (2 mL) was placed into an 8-mL sealed tube. The resulting solution was stirred overnight at 110 C. Then the reaction was concentrated to dryness, and the residue was diluted with 5 mL of methanol. The resulting solids were collected by filtration and washed with methanol. Drying afforded 158 mg (73%) of 3-(4-fluorophenyl)-5-(pyridin-3-yl)pyrazolo[1,5-a]pyrimidin-7(4H)-one as a yellow solid. LC-MS: (ES, m/z): 307 [M+H]+ 1H-NMR (300 MHz, DMSO, ppm): delta 12.37 (s, 1H), 9.05 (s, 1H), 8.77 (dd, J=1.5, 4.8 Hz, 1H), 8.26 (s, 2H), 7.76 (s, 1H), 7.61 (dd, J=4.8, 7.9 Hz, 1H), 7.31 (t, J=8.7 Hz, 2H), 6.17 (s, 1H)
