Participants

Reaction Steps

To a solution of 4-[5-[2-(3-fluorophenyl)ethyl]-1,3,4-oxadiazol-2-yl]pyridin-2-amine (280 mg, 0.985 mmol), triethylamine (0.82 mL, 5.92 mmol) and 4-dimethylaminopyridine (12 mg, 0.0985 mmol) in tetrahydrofuran (10 mL) was added benzyl chloroformate (0.70 mL, 4.92 mmol) at 0° C., and the resulting mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (hexane/ethyl acetate=95/5-0/100) and recrystallized from hexane/ethyl acetate to give the title compound (30 mg, yield 7%) as colorless crystals.
