Participants

Reaction Steps

To a solution of (4-fluorophenyl)(2-(piperazin-1-yl)pyrimidin-5-yl)methanone (4.0 g, 21.84 mmol) in dry THF (150 mL) was added EtMgBr (1 M in THF, 150 mL) at 0° C. under nitrogen. The mixture was stirred at RT for 3 h, then quenched with NH4Cl solution and extracted with ethyl acetate (200*3 mL). The combined organic layers were washed with water and brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by combi-flash with dichloromethane:methanol=10:1 to give the title compound (440 mg, 10%) as a yellow solid. MS (ES+) C17H21FN4O requires: 316. found: 317 [M+H]+.
