실험 절차

A solution of a mixture of 3-[4-(2-chloro-5-methoxypyrimidin-4-yl)-1H-pyrazol-1-yl]-3-cyclopropylpropanenitrile (from example 320 step 1, 60 mg, 0.0002 mol), m-nitroaniline (40.9 mg, 0.000296 mol), and p-toluenesulfonic acid (29 mg, 0.00017 mol) in dry 1,4-dioxane (1 mL, 0.02 mol) was refluxed overnight. The mixture was diluted with acetonitrile and water, purified on RP-HPLC at pH 10 to give the desired product as a racemic mixture (free base). LCMS (M+H) 406.2.
