The title compound was produced following the procedure of Example 13 using dimethylformamide as solvent, the thienopyrimidine-2,4-dione (3.0 g, 7.76 mmol) from Example 19, and ethyl 5-bromovalerate was used as the alkylating agent. The title compound was isolated in 82% yield (3.3 g), after recrystallization from EtOH, mp 118°-119° C.
