Hydrochloric Acid → 4-[3-(4-{3-Trifluoromethylphenyl}piperazinyl)propylthio]pyrimidine

참여 물질

반응 단계

1.5 g (13.4 mmol) of 4-mercaptopyrimidine, 4.3 g (14 mmol) of 1-(3-chloropropyl)-4-(3-trifluoromethylphenyl) piperazine and 1.5 g (15 mmol) of triethylamine in 5 ml of DMF were stirred at 100° C. for 1 hour. The mixture was then poured into 5% strength hydrochloric acid and extracted with MTB ether. The aqueous phase was made alkaline with sodium hydroxide solution and then extracted with ethyl acetate, and the organic phase was dried over MgSO4 and concentrated. The residue was purified by chromatography (mobile phase: CH2Cl2/CH3OH═98/2). 3.0 g of product were obtained as a yellowish oil (=59% yield).
