Participants

Reaction Steps

To the solution of N-(5-cyclopropyl-1H-pyrazol-3-yl)-5-iodo-2-phenylpyrimidin-4-amine (3 g, 7.44 mmol) in THF/H2O (50 mL/25 mL), a solution of Ac2O (1.5 g, 14.88 mmol, 2.0 equiv.) in THF (5 mL) was added dropwise. The reaction mixture was stirred at room temperature for 12 h. The reaction mixture was filtered to afford compound 1-(5-cyclopropyl-3-(5-iodo-2-phenylpyrimidin-4-ylamino)-1H-pyrazol-1-yl)ethanone (2.2 g, 66%). LC-MS (m/z): 446.0 [M+H]+.
