実験手順

To a solution of N-(5-(5-chloro-2-methoxyphenyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (prepared as described for Example 14, 115.4 mg, 0.313 mmol) in 3 mL DMF is added 1-(iodomethyl)cyclopentanol (195.4 mg, 2.762 mmol) and cesium carbonate (339.2 mg, 3.327 mmol). The reaction was stirred in a sealed vessel at 140° C. for 18 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 separated from the other regioisomeric product and purified by reverse phase HPLC and lyophilized to give 32.1 mg (22%) of N-(3-(5-chloro-2-methoxyphenyl)-1-((1-hydroxycyclopentyl)methyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=467.1; 1H NMR (400 MHz, DMSO-d6) δ: 9.68 (s, 1H), 9.33 (dd, J=7.0, 1.6, 1H), 8.77 (dd, J=4.2, 1.6, 1H), 8.64 (s, 1H), 8.33 (s, 1H), 7.49 (dd, J=8.9, 2.7, 1H), 7.39 (d, J=2.7, 1H), 7.32-7.25 (m, 2H), 4.67 (s, 1H), 4.19 (s, 2H), 3.84 (s, 3H), 1.61 (m, 8H).
