Reaction Steps

To a solution of 4-amino-6-chloropyrimidine (230 mg, 1.78 mmol) in DCM (15 mL) is added 6-(trifluoromethyl)picolinoyl chloride (276 mg, 1.78 mmol) and DIPEA (0.912 ml, 5.33 mmol). The mixture is stirred overnight at RT. The mixture is diluted with DCM (10 mL), washed with saturated NaHCO3 solution (25 mL). The organic layer is dried over MgSO4 and evaporated under reduced pressure. The residue is purified by prep HPLC E, delivering the title compound as a yellowish solid (102 mg, 19%); LC-MS A: tR=0.89 min; [M+H]+=302.92.
