Potassium Carbonate → 3-(2-(4-(3-chlorophenyl)piperazin-1-yl)-2-oxoethyl)-5-methyl-6-(pyrrolidine-1-carbonyl)thieno[2,3-d]pyrimidin-4(3H)-one

Participants

Reaction Steps

To a suspension of 5-methyl-6-(pyrrolidine-1-carbonyl)thieno[2,3-d]pyrimidin-4(3H)-one, (0.06 g, 0.23 mmol) in CH3CN (5 mL) was added K2CO3 (0.032 g, 0.23 mm (38 mg, 0.23 mmol), and 2-chloro-1-(4-(3-chlorophenyl)piperazin-1-yl)ethanone, (0.062 g, 0.23 mmol). The reaction mixture was refluxed overnight and then quenched with H2O (20 mL). The resultant precipitate was filtered and dried to provide a crude solid which was purified by flash chromatography (Et2O:DCM, 1:1) providing 0.025 g of pure 3-(2-(4-(3-chlorophenyl)piperazin-1-yl)-2-oxoethyl)-5-methyl-6-(pyrrolidine-1-carbonyl)thieno[2,3-d]pyrimidin-4(3H)-one, (yield: 22%).
