Hydrochloric Acid → HCID 90370342, compound

Participants

Reaction Steps

A mixture of 194 mg of methyl 4-[2-(4-{[(2-{[3-({cyclopropyl[2-(methylamino)ethyl]amino}methyl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate, 0.050 mL of (2-methoxyethoxy)acetic acid, 84 mg of WSC.hydrochloride, and 5.0 mL of DMF was stirred for 15 hours at room temperature. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate, and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (5% methanol/chloroform), thereby obtaining 200 mg of methyl 4-[2-(4-{[(2-{[3-(11-cyclopropyl-8-methyl-7-oxo-2,5-dioxa-8,11-diazadodecan-12-yl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate.
