Reaction Steps

A mixture of 2,4-dichloro-5-fluoropyrimidine (167 mg, 1.00 mmol), nipecotamide (128 mg, 1.00 mmol) and DIEA (0.350 mL, 2.01 mmol) in CH3CN (4 mL) was stirred at room temperature for 20 h. It was concentrated in vacuo. The residue was dissolved in nBuOH (4 mL). 2 mL of the nBuOH solution was taken, to which 1-(4-(4-aminophenyl)piperazin-1-yl)ethanone (150 mg, 0.68 mmol) was added. The solution was stirred at 116° C. for 6 h. nBuOH was removed in vacuo. The residue was purified by HPLC to give the titled compound (75 mg). MS 442.4 (M+H); UV 208.8, 261.8 nm.
