1-Hydroxybenzotriazole → HCID 21084519, 화합물

참여 물질

반응 단계

In chloroform (5.0 ml), 5-t-butoxycarbonylaminovaleric acid (387 mg), WSCI hydrochloride (466 mg), and HOBt (328.3 mg) were dissolved. Then, the solution was stirred at room temperature for 1 hour. A solution (3.0 ml) of 3-amino-4-propylaminobenzonitrile (283 mg) in chloroform was dropped in this solution. Then, the solution was stirred overnight at room temperature. After completion of the reaction, the solvent was distilled off under reduced pressure. The residue was dissolved in chloroform and then washed with a saturated aqueous sodium bicarbonate solution, a saturated aqueous ammonium chloride solution, and saturated saline solution, followed by drying with anhydrous sodium sulfate. After filtration, the solvent was distilled off under reduced pressure and the residue was then purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound as a colorless viscous substance.
