1-Hydroxybenzotriazole → 5-[5-(2,6-Dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-ethylsulfanyl-ethyl)-amide

Participants

Reaction Steps

A mixture of 5-[5-(2,6-dichloro-phenylmethanesulfonyl)-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (100 mg, 0.2 mmol), HOBt (32 mg, 1.2 eq.), EDAC.HCl (45 mg, 1.2 eq.), TEA (0.138 mL, 5 eq.) and 2-ethylsulfanyl-ethylamine hydrochloride salt (69 mg, 2.5 eq.) in DMF (2 mL) was stirred at rt for 7 days. The reaction was concentrated, diluted with DCM, washed with sat. NaHCO3 and water, dried, concentrated and purified on a silica gel column to give the titled compound as a yellow waxy solid.
