Reaction Steps
To a suspension of (R)-1-(5-(2,2,2-trifluoroethoxy)pyridin-2-yl)ethanamine 2HCl salt (173 mg, 0.79 mmol) and 2-(4-bromophenoxy)acetic acid (200 mg, 0.87 mmol) in dichloromethane (5 mL) were added triethylamine (400 mg, 3.9 mmol), EDC (180 mg, 0.94 mmol) and HOBT (60 mg, 0.39 mmol) respectively. The reaction mixture was stirred at room temperature for 18 hours. Sat. ammonia hydrochloride aqueous solution was added to the mixture. The organic layer was extracted with ethyl acetate, washed with brine, and dried over sodium sulfate. After the filtration to separate solvent and sodium sulfate, the solvent was removed under reduced pressure to give the residue, which was applied to a silica gel chromatography column and eluted with a hexane/ethylacetate=2/1 (v/v) to furnish 276 mg (81% yield) of the title as a colorless oil;
