반응 단계
To a solution of 4-amino-3-chloro-benzoic acid (1 equiv) in DCM (0.12 M) was added N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (1.2 equiv), 1-hydroxybenzotriazole (1.2 equiv), triethylamine (4 equiv) and dimethylamine hydrochloride (2 equiv) sequentially. The mixture was stirred at room temperature overnight. After the reaction was complete, as monitored by LCMS, the mixture was diluted with a mixture of isopropanol in chloroform (30%,), washed with water and dried over anhydrous sodium sulfate. The organic phase was concentrated and the residue obtained was recrystallized in the mixture of hexane and ethyl acetate (10%,) to afford the desired product (Yield: 59.6%) as a light brown solid. MS (ESI) m/z 199.1 [M+1]+.
