Versuchsvorschrift

3-Chloro-4-methoxybenzyl alcohol (20 g, 116 mmol) was dissolved in 200 mL of DMF, NaH (7.0 g, 174 mmol) was added under ice-water-bath. After 1 h of reaction, ethyl 4-chloro-2-(methylmercapto)pyrimidine-5-carboxylate (27 g, 116 mmol) was added in portions for continuing the reaction for 3 h. 300 mL of water was added, extraction was performed with ethyl acetate, the organic layer was dried, concentrated and separated with silica gel column (petroleum ether: ethyl acetate=10:1) to obtain ethyl 4-(3-chloro-4-methoxybenzyloxy)-2-(methylmercapto)pyrimidine-5-carboxylate as white solid (5.0 g, 12%).
