실험 절차

To a solution of 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylic acid, (2 g, 9.5 mmol) in DMF (20 mL) was added DIEA (5 mL, 28.5 mmol), 1-(3-chlorophenyl)piperazine hydrochloride (2.2 g, 9.5 mmol), and HATU (4.7 g, 12.3 mmol). The reaction mixture was stirred at RT overnight. The reaction mixture was diluted with EtOAc (60 mL) and the organic layer was washed successively with sat. NaHCO3 aq. (50 mL) and brine (50 mL). The organic layer was separated, dried over Na2SO4, and concentrated to give crude product as a gummy solid. Purification by flash column chromatography using EtOAc as the eluent afforded the 3 g of pure 6-(4-(3-chlorophenyl)piperazine-1-carbonyl)-5-methylthieno[2,3-d]pyrimidin-4(3H)-one, (yield: 81%).
