Procedure: The reaction mixture of 100.0 mg (0.37 mmol) of 4-chloro-3-ethoxycarbonyl-5,8-difluoroquinoline, 80.3 mg (0.44 mmol) of 3-trifluoromethylthiophenol and 80 μL of diisopropylethylamine in 2.0 mL of N,N-dimethylformamide was stirred at room temperature for 2 h and cooled. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulphate and concentrated. The resulting residue was purified on silica gel column eluting with ethyl acetate-hexane (1:3) to give 30.0 mg (20%) of the title compound. cooled extracted with ethyl acetate The organic layer was washed with brine dried over magnesium sulphate concentrated The resulting residue was purified on silica gel column eluting with ethyl acetate-hexane (1:3)

Procedure: The reaction mixture of 151.8 mg (0.50 mmol) of 4-chloro-3-ethoxycarbonyl-6-trifluoromethylquinoline, 106.9 mg (0.60 mmol) of 3-trifluoromethylthiophenol and 100 μL of diisopropylethylamine in 2.0 mL of N,N-dimethylformamide was stirred at room temperature for 2 h and cooled. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulphate and concentrated. The resulting residue was purified on silica gel column eluting with ethyl acetate-hexane (1:3) to give 76.4 mg (34%) of the title compound. cooled extracted with ethyl acetate The organic layer was washed with brine dried over magnesium sulphate concentrated The resulting residue was purified on silica gel column eluting with ethyl acetate-hexane (1:3)

Procedure: To N,N-dimethylformamide (30 ml) and 2-(7-bromoheptyl)benzaldehyde (1.5 g, 5 mmoles) was added a solution of 3-trifluoromethylthiophenol (1.0 ml, 8 mmoles) and triethylamine (3.0 ml, 0.02 mole) in N,N-dimethylformamide (20 ml). The reaction mixture was heated to 90° C. for 1 hour and then stirred for 11/2 hours while slowly cooling to room temperature. The mixture was diluted with toluene and evaporated, followed by dilution with methylene chloride. The solution was evaporated and flash chromatographed using 8% ethyl acetate in hexane to give the desired product. while slowly cooling to room temperature evaporated The solution was evaporated flash chromatographed

Procedure: m-Trifluoromethylbenzenethiol (5 g) was added to a solution of NaOH (2.25 g) in ethanol (50 ml) and the resulting solution was treated with a solution of 2-picolyl chloride, hydrochloride (4.6 g) in ethanol (25 ml) and the mixture was stirred for 5 hours. The resulting suspension was filtered through kieselghur and the solvent was removed by evaporation. The residue was converted into the hydrochloride in ether with ethereal HCl and recrystallised from acetone-ether to give 2-(((3-trifluoromethylphenyl)thio)methyl)pyridine hydrochloride (4.8 g) mp 145°-6° C. (Found: C,51.1; H,4.0; N,4.7 C13H10F3NS.HCl requires C,51.0; H,3.6; N,4.6%). The resulting suspension was filtered through kieselghur the solvent was removed by evaporation recrystallised from acetone-ether
