Potassium Carbonate → 1-{2-Fluoro-4-[3-(1-quinolin-6-ylcyclopropyl)imidazo[1,2-a]pyrimidin-6-yl]phenyl}pyrrolidin-2-one

Participants

Reaction Steps

To a solution of 6-{1-[6-(4-bromo-3-fluorophenyl)imidazo[1,2-a]pyrimidin-3-yl]cyclopropyl}quinoline (20 mg, 0.04 mmol) in 1,4-dioxane (1 mL) was added 2-pyrrolidinone (5.7 mg, 0.067 mmol), (1S,2S)—N,N′-dimethylcyclohexane-1,2-diamine (1 mg, 0.009 mmol), copper(I) iodide (0.8 mg, 0.004 mmol), and potassium carbonate (13 mg, 0.095 mmol). The mixture was irradiated at under microwave 150° C. for 1 h. After cooling to RT, the solution was purified by RP-HPLC (pH=10) to afford the desired compound. LCMS: (M+H)+=464.1.
