4-Toluenesulfonyl chloride → (S)-2-[p-(3-Chlorobutyloxy)phenyl]-5-n-hexylpyrimidine

Participants

Reaction Steps

26.3 g of (S)-3-chlorobutyl-1-tosylate, preparable from p-toluenesulfonyl chloride and (S)-3-chlorobutan-1-ol, and 27.2 g of 4-(5-n-hexylpyrimidin-2-yl)phenol are added to a suspension of 40 g of potassium carbonate in 200 ml of acetone. After 24 hours' boiling under reflux, the reaction mixture is filtered, the filtrate is freed from solvent and the residue is twice recrystallized from ethanol. (S)-2-[p-(3-Chlorobutyloxy)phenyl]-5-n-hexylpyrimidine is obtained.
