실험 절차

To a solution of 1-isopropylindole-3-carboxylic acid (159.6 mg, 0.785 mmol) in methylene chloride (3.5 ml) was added oxalyl chloride (101.0 μl, 1.178 mmol) under stirring at −15° C. The reaction mixture was stirred for 2.5 hours at room temperature and then distilled under reduced pressure to remove the solvent. The residue was dissolved in methylene chloride (3.5 ml), followed by the addition of a solution of methyl 3-chloro-4-aminophenylacetate (164.6 mg, 0.824 mmol) in methylene chloride (3.5 ml) and triethylamine (0.35 ml, 2.474 mmol) under stirring at room temperature. The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was then distilled under reduced pressure to remove the solvent. The residue was dissolved in chloroform. The resulting solution was washed successively with 1N HCl and saturated saline, dried over anhydrous sodium sulfate and distilled under reduced pressure to remove the solvent, whereby methyl 3-chloro-4-((1-isopropyl-3-indolylcarbonyl)amino)phenylacetate (275.3 mg, 91%) was obtained as a brown solid. The resulting compound was provided for the subsequent reaction without further purification.
