Participants

Reaction Steps

To the mixture of 5-bromo-N-(5-cyclopropyl-1H-pyrazol-3-yl)-2-phenylpyrimidin-4-amine (200 mg, 0.56 mmol, 1.0 eq) in THF (8 mL) and water (5 mL) was added a solution of Ac2O (0.18 mL, 1.68 mmol, 3.0 eq) in THF (2 mL). The reaction mixture was stirred for 14 hours and water was added. The mixture was filtered and the solid was washed with water and dried by co-evaporated with ethanol to give 1-(3-(5-bromo-2-phenylpyrimidin-4-ylamino)-5-cyclopropyl-1H-pyrazol-1-yl)ethanone (150 mg, 67%). LC-MS (m/z)=398.0, 400.0 [M+H]+.
