Reaction Steps

DIEA (121 mg, 0.94 mmoL) was added to at 0° C. a mixture of 1-(7-amino-3-(6-phenylpyridin-3-yl)-5-(piperidin-4-yl)pyrazolo[1,5-a]pyrimidin-6-yl)ethanone (64.3 mg, 0.15 mmoL) and morpholine-4-sulfonyl chloride (28.9 mg, 0.15 mmol) in DMF (3 mL). After stirring at 0° C. for 0.5 h and then room temperature for 2 h, the mixture was purified by prep-LC to afford 1-(7-amino-5-(1-(morpholinosulfonyl)piperidin-4-yl)-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-6-yl)ethanone, LCMS tR=3.83 Min (5 min run, UV254nm). Mass calculated for, M+ 561.66, observed LC/MS m/z 567.66 (M+H).
