Reaction Steps

N-[2-(4-trifluoromethylphenoxy)ethyl]-formamide (2.02 g, 8.66 mmol) prepared in Reference Example 160 was dissolved in THF (20 ml). Borane-THF complex (1 M) THF solution (21.7 ml, 21.7 mmol) was added dropwise to this solution while cooling in an ice-bath, and the mixture was stirred overnight. The reaction mixture was cooled, to which water and 6N hydrochloric acid were added, and the mixture was stirred for 20 minutes. The reaction mixture was neutralized with a sodium hydroxide aqueous solution, and the mixture extracted with methylene chloride. The extract was dried over magnesium sulfate, and then filtered. The filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (methylene chloride/methanol=200/1) to afford N-methyl-N-[2-(4-trifluoromethylphenoxy)ethyl]amine (1.05 g, yield 55%) as a white powder.
