1-Hydroxybenzotriazole → HCID 23155436, 화합물

참여 물질

반응 단계

In chloroform (10 ml), 5-t-butoxycarbonylaminovaleric acid (574 mg), WSCI hydrochloride (690 mg), and HOBt (487 mg) were dissolved. Then, the resulting solution was stirred at room temperature for 30 minutes. The solution was added with 4-amino-3-propylaminobenzoic acid methyl (503 mg) and stirred overnight at room temperature. After completion of the reaction, the solvent was distilled off under reduced pressure and the residue was then dissolved in chloroform. After having been washed with a saturated aqueous sodium bicarbonate solution, a saturated aqueous ammonium chloride solution, and saturated saline solution, the solution was dried 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 (540 mg) as a colorless viscous substance.
