YieldReaction ConditionsOperation in experiment
65% With toluene-4-sulfonic acid; In butan-1-ol; for 2h;Reflux; To a solution of 4-(4-methylthiazol-2-yl)-lH-pyrazol-5-amine (50 mg, 0.27 mmol) in n-BuOH (1.0 mL) was added p-TsOH (4.7 mg, 0.03 mmol) and ethyl 3-(3,4- dichlorophenyl)-3-oxopropanoate (108 mg, 0.41 mmol). The reaction was stirred for 2 h at reflux, then cooled to room temperature and diluted with methanol (1 mL). The solids were collected by filtration and washed with MeOH (3 x 1 mL) to afford 5-(3,4-dichlorophenyl)-3-(4-methylthiazol-2-yl)pyrazolo[l ,5-a]pyrimidin- 7(4H)-one as a white solid (68.9 mg 65%). LCMS (ES, m/z): [M+l] +: 377.0 *H NMR (300 MHz, CD3OD): delta 8.46 (s, 1H), 8.43 (d, / = 2.1 Hz, 1H), 8.11 (dd, J 1= 2.1 Hz, J = 8.4 Hz, 1H), 7.62 (d, / = 8.4 Hz, 1H), 6.97 (s, 1H), 6.38 (s, 1H), 2.45 (s, 3H)
