Then the extracts weredried over anhydrous Na2SO4, filtered, and the solvent wasevaporated to dryness to give the crude product. Solids werepurified through recrystallization in absolute EtOH, and liquids were purified over a silica gel column using hexane:EtOAc (96:4) as the eluent. The successful formation of theproducts was confirmed by 1H NMR, 13C NMR and FT-IRspectra.

YieldReaction ConditionsOperation in experiment
95% With sodium hydroxide; N-chloro-succinimide; In dichloromethane; (c) 4-Methoxy-6-(methylthiomethyl)-2-(alpha,alpha,alpha-trifluoromethyl)aniline was prepared by substituting 4-methoxy-2-(alpha,alpha,alpha-trifluoromethyl)aniline as follows: In a 250 ml three-necked flask equipped with an overhead stirrer was placed 20.12 g (0.105 mol) of 4-methoxy-2-(alpha,alpha,alpha-trifluoromethyl)aniline in 100 ml of methylene chloride. To the solution was then added 15.63 g (0.117 mol) of N-chlorosuccinimide was added with vigorous stirring. After cooling to 0 C. under a nitrogen atmosphere, a solution of 9.2 ml (8.02 g, 0.129 mol) dimethylsulfide in 40 ml of methylene chloride was then added over a one hour period while maintaining the temperature below 5 C. The reaction mixture became very thick. The ice bath was removed and after stirring at room temperature for one hour, 200 ml of ice cold 5% aqueous sodium hydroxide solution was added. The methylene chloride layer was separated, dried over anhydrous potassium carbonate, filtered and the solvent removed under reduced pressure. To the residue was then added 60 ml of 1,2-dichloroethane and 1.00 g (10 mmol) of succinimide. After refluxing for twelve hours under a nitrogen atmosphere, the reaction mixture was cooled, washed twice with 100 ml of 5% sodium hydroxide solution, dried with magnesium sulfate, filtered and concentrated under reduced pressure to afford 24.9 g of a black oil. This was distilled under reduced pressure to afford 16.5 g (63% yield) of the desired product as a clear, colorless liquid (Bp 106-110 at 0.35 mm Hg) of 95% purity as assayed by gas chromatography; 1 H NMR analysis indicated: (delta, CDCl3) 6.94 (d, J=1.8 Hz, 1H), 6.78 (d, J=1.8 Hz, 1H), 4.32 (br s, 2H, NHz), 3.54 (s, 3H), 3.51 (s, 2H) and 1.82 (s, 3H).
