Dimethylformamide → {1-[(5-Chloro-2,4-dimethoxy-phenylcarbamoyl)-methyl]-2,4-dioxo-1,4-dihydro-2H-pyrido[3,4-d]pyrimidin-3-yl}-acetic acid tert-butyl ester

Participants

Reaction Steps

A 25 ml round bottomed flask is charged with (2,4-dioxo-1,4-dihydro-2H-pyrido[3,4-d]pyrimidin-3-yl)-acetic acid tert-butyl ester (23.9 mg, 0.086 mmol), 2-bromo-N-(5-chloro-2,4-dimethoxy-phenyl)-acetamide (30.5 mg, 0.095 mmol) and Cs2CO3 (84.6 mg, 0.172 mmol). The mixture is treated with DMF (2 ml) and the solution stirred at RT overnight. Water is added to the mixture giving rise to a solid. This is filtered, dried, and purified via flash column chromatography, eluting with iso-hexane:EtOAc to give the title compound.
