Reaction Steps

tert-Butyl 2-(2-(2-aminoethyl)disulfanyl)ethylcarbamate (150 mg, 0.595 mmol) was taken up in CH2C22 (10 mL) along with indomethacin (213 mg, 0.595 mmol) and EDCI (125 mg, 0.65 mmol). The resulting reaction mixture was stirred at room temperature for 18 h and diluted with CH2Cl2. The organic layer was washed with saturated aqueous NaHCO3, brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by chromatography (CH2Cl2) to afford 312 mg of tert-butyl 2-(2-(2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetamido)ethyl)disulfanyl)ethylcarbamate (89% yield).
