p-Toluenesulfonic acid → 1-(cyclopropylsulfonyl)-4-(4-(2-(4-(1H-pyrazol-1-yl)phenyl)aminopyrimidin-4-yl)-1H-pyrazol-1-yl)piperidin-4-ylacetonitrile

Participants

Reaction Steps

A mixture of (4-(4-(2-chloropyrimidin-4-yl)-1H-pyrazol-1-yl)-1-(cyclopropylsulfonyl)piperidin-4-yl)acetonitrile (30 mg, 0.08 mmol), 4-(1H-pyrazol-1-yl)aniline (18.9 mg, 0.119 mol), and p-toluenesulfonic acid (12 mg, 0.067 mmol) in dry 1,4-dioxane (0.6 mL) was refluxed overnight. The mixture was diluted with acetonitrile and water, purified on RP-HPLC at pH 10 to give the desired product as free base (30 mg, 72%). LCMS (M+H) 530.1.
