Versuchsvorschrift
To a solution of N-(3-(5-chloro-2-hydroxyphenyl)-1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (61.1 mg, 0.166 mmol) in 3.0 mL acetone was added iodoethane (26.0 μL, 0.325 mmol) and potassium carbonate (70.6 mg, 0.511 mmol) The reaction was stirred at 45° C. for 3 hours. The reaction mixture was partitioned between ethyl acetate and water, and the organic portion washed with brine, dried over magnesium sulfate, and concentrated. The crude product was purified by reverse phase HPLC and lyophilized to give 34.8 mg (54%) N-(3-(5-chloro-2-ethoxyphenyl)-1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=397.1; 1H NMR (400 MHz, DMSO-d6) δ: 9.68 (s, 1H), 9.33 (dd, J=7.0, 1.6, 1H), 8.73 (dd, J=4.2, 1.6, 1H), 8.66 (s, 1H), 8.28 (s, 1H), 7.46 (dd, J=8.8, 2.7, 1H), 7.38 (d, J=2.7, 1H), 7.32-7.23 (m, 2H), 4.12 (q, J=6.9, 2H), 3.91 (s, 3H), 1.04 (t, J=6.9, 3H).
