2-(2-((4-Chloro-2-(methoxycarbonyl)phenyl)amino)-2-oxoethoxy)acetic acid → HCID 44250489, compound

Participants

Reaction Steps

Using the same method as in Example 1-(ii), 3-(furan-3-yl)benzylamine.hydrochloride was reacted with the (2-([4-chloro-2-(methoxycarbonyl)phenyl]amino)-2-oxoethoxy)acetic acid obtained in Example 1-(i) to give 5-chloro-2-([(2-([3-(furan-3-yl)benzyl]amino)-2-oxoethoxy)acetyl]amino)benzoic acid.methyl ester (yield: 77%). Note that 3-(furan-3-yl)benzylamine.hydrochloride was neutralized in DMA by adding an equivalent amount of triethylamine, and then used in the reaction.
