Reaction Steps

Methylamine (37.2 ml of a 40% by weight aqueous solution, 481 mmole) was added to a 250 ml flask containing 4.47 g (12.0 mmole) of 3-phenyl-4-(4-trifluoromethylphenyl)butane sulfonic acid methyl ester dissolved in 50 ml of tetrahydrofuran. The resulting solution was stirred overnight at room temperature (22° C.) and concentrated under reduced pressure to provide a residue. The residue was dissolved in ethyl acetate and the resulting solution was washed with water and a saturated brine solution. The organic solution was dried over anhydrous sodium sulfate and the volatiles were removed under reduced pressure to provide 3.5 g of N-methyl-3-phenyl-4-(4-trifluoromethylphenyl)butanamine as an oil. A sample of the oil was crystallized from an acetone/diethyl ether solution containing 1.5 equivalents of concentrated hydrochloric acid to yield N-methyl-3-phenyl-4-(4-trifluoromethylphenyl)butanamine hydrochloride as white crystals. mp=156°-157.5° C.
