Versuchsvorschrift

To a solution of 3-(2-(3,5-bis(trifluoromethyl)phenylamino)-2-oxoethyl)-5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylic acid (0.24 g, 0.5 mmol) in DCM (5 mL) was added DIEA (0.3 mL, 1.5 mmol), 2-fluorophenylpiperazine (0.060 mL, 0.5 mmol), and HATU (0.25 g, 0.65 mmol). The reaction mixture was stirred at RT overnight. The organic layer was washed with sat. NaHCO3 aq. (20 mL), dried over Na2SO4, and concentrated to give crude product as a gummy solid. Purification by flash column chromatography using a mixture of Et2O:DCM (1:1) as the eluant afforded the 0.19 g of the desired product N-(3,5-bis(trifluoromethyl)phenyl)-2-(6-(4-(2-fluorophenyl)piperazine-1-carbonyl)-5-methyl-4-oxo thieno[2,3-d]pyrimidin-3(4H)-yl)acetamide, (yield: 60%).
