Procedure
A mixture of 1-(7-amino-5-(3,8-diazabicyclo[3.2.1]octan-3-yl)-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-6-yl)ethanone (11 mg, 0.025 mmol), 4H-1,2,4-triazole-3-carboxylic acid (3.1 mg, 0.027 mmol), EDCI (9.5 mg, 0.05 mmol), HOBt (6.75 mg, 0.05 mmol) and DIEA (26 ul, 0.15 mmol) in DMF (1 ml) was stirred at room temperature overnight. Purification with prep-LC provided 1-(5-(8-(4H-1,2,4-triazole-3-carbonyl)-3,8-diazabicyclo[3.2.1]octan-3-yl)-7-amino-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-6-yl)ethanone, LCMS tR=3.31 Min (10 min run, UV 254 nm). Mass calculated for M+H 535.2, observed LC/MS m/z 534.95 (M+H).
