Participants

Reaction Steps

To a solution of ethyl 4-{[(1H-indol-6-ylmethyl)(4-methylisoquinolin-3-yl)amino]sulfonyl}benzoate (177 mg, 0.36 mmol) prepared in Example 116 in tetrahydrofuran (1.8 mL) was added N-chlorosuccinimide (57 mg, 0.43 mmol) at room temperature, and the mixture was stirred for 17 hours. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1→1:1) to give ethyl 4-{[[(3-chloro-1H-indol-6-yl)methyl] (4-methylisoquinolin-3-yl)amino]sulfonyl}benzoate (124 mg, 65%) as a white solid.
