実験手順

To a solution of 2-(3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)azetidin-3-yl)acetonitrile hydrochloride (Example 62; 20 mg, 0.046 mmol) in THF (460 μL, 0.046 mmol) was added triethylamine (19 μL, 0.14 mmol) and acetic anhydride (5.7 mg, 0.056 mmol). After stirring at ambient temperature for 30 minutes, the reaction mixture was diluted in water. The reaction mixture was directly purified by reverse phase HPLC using a 0-100% acetonitrile/water gradient to afford 2-(1-acetyl-3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)azetidin-3-yl)acetonitrile (15 mg, 0.038 mmol, 82% yield) as a fluffy white solid. MS (apci) m/z=402.2 (M+H).
