Reaction Steps
To a solution of 4,6-dichloro-2-methylsulfanylpyrimidine (500 mg, 2.56 mmol) in anhydrous DMF (6 mL) was added sodium ethoxide (174 mg, 2.56 mmol). The reaction mixture was stirred at 70° C. for overnight. The resulting mixture was poured into 30 mL of water and was extracted with diethyl ether (20 mL×3) three times. The ether layer was separated and dried with anhydrous MgSO4 and concentrated in vacuo to give crude product 4-chloro-6-ethoxy-2-methylsulfanylpyrimidine (525 mg). 1H-NMR (CDCl3): δ 6.39 (s, 1H), 4.43 (q, J=7.1 Hz, 2H), 2.54 (s, 3H), 1.38 (t, J=7.1H, 3H).
