Participants

Reaction Steps

After this compound, ethyl 3-(isopropoxy)-2-p-toluenesulfonyloxybutanoate (27.5 g, 0.08 mol) and 4,6-dimethoxy-2-mercaptopyrimidine (13.7 g, 0.08 mol) were added to N,N-dimethylformamide (80 ml) and further anhydrous potassium carbonate (11.1 g) was added thereinto, the mixture was stirred at room temperature for 5 hours. Subsequently, water was added to the reaction mixture, the mixture was extracted with ethyl acetate, washed with water and dried, and ethyl acetate was removed under reduced pressure. The residue obtained was isolated by column chromatography (Wako gel C-200 (trade name, produced by Wako Junyaku K.K.), eluted by hexane:ethyl acetate=8:1) to obtain 15.0 g (yield: 54.5%) of the title compound as a colorless oily product.
