Procedure

To a suspension of methyl 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylate (2.24 g, 10 mmol) in CH3CN (25 mL) was added K2CO3 (1.38 g, 10 mmol), KI (1.61 g, 10 mmol), and 2-chloro-N-cyclohexylacetamide (1.75 g, 10 mmol). The reaction mixture was refluxed overnight and quenched with H2O (120 mL). The resulting precipitate was filtered and dried to afford methyl 3-(2-(cyclohexylamino)-2-oxoethyl)-5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylate, as a solid (yield: quantitative).
