Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials.92-30-8,A new synthetic method of this compound is introduced below.92-30-8
92-30-8, Compound 2; 10-(3-Chloropropyl)-2-trifluoromethylphenothiazine; To a stirred solution of 2-trifluoromethyl phenothiazine (compound 1) (2g, 7.49 mmol) and sodium hydride (0.5 g, 10.42 mmol) in dry toluene (30 mL) was added l-bromo-3-chloropropane (1.57g, 10 mmol). The reaction mixture was stirred for 18 hours at 110 C under an atmosphere of argon. The solution was cooled to room temperature and poured into an ice- water mixture, the crude product was extracted with ethyl acetate (3×50 mL) and the combined organic phase dried over anhydrous sodium sulphate. Final purification was performed by column chromatography (9:1 hexane: ethyl acetate) on silica gel to give 10-(3- chloropropyl)- 2-trifluoromethylphenothiazine (1.5 g, 58% ) as a solid.
