Participants

Reaction Steps

A mixture of ethyl 4-({(1-cyclopropyl-4-methylisoquinolin-3-yl)[4-(trifluoromethoxy)-benzyl]amino}sulfonyl)benzoate (92.0 mg, 157 μmol) prepared in Example 9, 2 mol/L aqueous sodium hydroxide solution (79 μl, 157 μmol) and ethanol (1.57 ml) was heated to reflux for 1 hour. The reaction solution was concentrated under reduced pressure, and the resulting residue was washed with diethyl ether and pentane to give sodium 4-({(1-cyclopropyl-4-methylisoquinolin-3-yl)[4-(trifluoromethoxy)benzyl]amino}sulfonyl)benzoate (86.6 mg, 95%) as a colorless powder.
