실험 절차

A mixture of 3-(5-chloro-2-methoxyphenyl)-1-methyl-1H-pyrazol-4-amine (258 mg, 0.869 mmol, 1.00 eq), pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (157 mg, 0.961 mmol, 1.11 eq), 7-azabenzotriazol-1-yloxy-tris-(pyrrolidino)phosphonium hexafluorophosphate (541 mg, 1.04 mmol, 1.20 eq), N,N-diisopropylethylamine (0.40 mL, 2.3 mmol, 2.6 eq), and 4-dimethylaminopyridine (30.7 mg, 0.251 mmol, 0.29 eq) in 8.0 mL N,N-dimethylformamide was stirred at 50° 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 to yield 232.3 mg (70%) of the crude product. The crude product was purified by reverse phase HPLC and lyophilized to give N-(3-(5-chloro-2-methoxyphenyl)-1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=383.0; 1H NMR (400 MHz, DMSO-d6) δ: 9.66 (s, 1H), 9.32 (d, 1H), 8.76 (d, 1H), 8.65 (s, 1H), 8.26 (s, 1H), 7.48 (d, 1H), 7.40 (s, 1H), 7.28 (m, 2H), 3.91 (s, 3H), 3.84 (s, 3H).
