반응 단계

To a solution of 35.7 g (0.22 mol) of 4-chloro-2-methylthiopyrimidine (Aldrich Chemical Co., Milwaukee, Wis., USA) in 135 mL of tetraglyme was added 18-crown-6 (1.33 g) and potassium fluoride (Anhydrous, Aldrich Chemical Co., Milwaukee, Wis., USA, 80 g). The mixture was heated at 150° C.with stirring for 16 hours. The mixture was then cooled and distilled under reduced pressure to give 20 g (62%) of 4-fluoro-2-methylthiopyrimidine as a liquid.
