実験手順

2-(1-Chloroethyl)-4,6-dimethoxypyrimidine 15.5 g (76.5 mmol) was dissolved in DMF 200 ml and sodium salt of methylmercaptan 5.4 g (76.5 mmol) was added thereto at room temperature. The solution was stirred at 50° C. for 1 hour. The reaction solution was poured into water and extracted with ethyl acetate. The solvent was distilled off and the residue was purified with column chromatography (hexane/ethyl acetate=5/1) to obtain 2-(1-methylthioethyl)-4,6-dimethoxypyrimidine 14.8 g (90%).
