Compound 13; 10-[3-(N-Boc-4-piperidyl)propyl]-2-trifluoromethylphenothiazine; To a stirred solution of 2-trifluoromethylphenothizine 1 (400 mg, 1.5 mmol), sodium hydride (100 mg, 2 mmol) in DME (10 mL) at 90 C was added N- Boc-4-(3-bromopropyl)piperidine 12 (380 mg, 1.24 mmol) dropwise under an atmosphere of argon. The reaction mixture was stirred for 12h at reflux. The reaction mixture was filtered and the filtrate was concentrated under vacuum. The residue was partitioned between ethyl acetate (25 mL) and brine (1OmL). The organic layer was dried over anhydrous sodium sulphate, filtered, and evaporated. The resulting residue was purified by silica gel column chromatography (8:2 hexane : ethyl acetate) on silica gel to give phenothiazine derivative 13 (425 mg, 70percent) as a solid. MS(ESI): m/z493 (M+H).
