Participants

Reaction Steps

To a solution (2 ml) of 4-(3-carboxyphenyl)-6-chloro-2-(4-methanesulfonylbenzyl)-1-oxo-1,2-dihydroisoquinoline-3-carboxylic acid methyl ester (100 mg) and 3-morpholin-4-ylpropylamine (31 μl) in acetonitrile were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (69 mg) and 4-hydroxybenzotriazole monohydrate (38 mg) at room temperature with stirring and the mixture was stirred at room temperature for 12 hrs. The solvent was removed under reduced pressure and the residue was partitioned between ethyl acetate and 1N hydrochloric acid. The organic layer was dried and concentrated to dryness. The residue was purified by silica gel column chromatography (ethyl acetate/methanol=10/1) to give the title compound (93 mg) as colorless crystals.
