Reaction Steps

5-(6-methyl-pyridin-3-yl)-1H-pyrimidine-2,4-dione hydrochloride (Prep57, 385 mg, 1.62 mmol), K2CO3 (224 mg, 1.62 mmol) and 3-bromo-1,1dimethoxy-propane (commercially available from Aldrich, 183 mg, 1.0 mmol) were suspended in dry DMF (8 mL). After stirring the reaction at room temperature for 24 hours, additional 3-bromo-1,1dimethoxy-propane (180 mg, 0.98 mmol) was added portionwise over a period of 96 h. Water was added and the mixture washed with diethyl ether. The aqueous layer was then extracted with ethyl acetate. The organic phase was dried (Na2SO4) and evaporated to give 320 mg of the final compound that was used without further purification in the next step (48% yield).
