Reaction Steps

A mixture of 2,4-dichloro-5-fluoropyrimidine (167 mg, 1.00 mmol), 4-piperidinemethanol (115 mg, 1.00 mmol) and DIEA (0.400 mL, 2.30 mmol) in CH3CN (4 mL) was stirred at room temperature for 2 h. It was concentrated in vacuo. The residue was dissolved in nBuOH (6 mL). 3 mL of the nBuOH solution was taken, to which 1-(4-(4-aminophenyl)piperazin-1-yl)ethanone (120 mg, 0.55 mmol) was added. The solution was stirred at 116° C. for 20 h. nBuOH was removed in vacuo. The residue was purified by HPLC to give the titled compound (53 mg). MS 429.3 (M+H); UV 207.8, 266.8 nm.
