실험 절차

A stirred solution of (0.547 g) of 2-(N-phenylsulfonylindol-3-yl)-4-carboxy-6,7-dimethoxyquinoline, K2CO3 (0.380 g), MeOH (40 ml) and H2O (10 ml) are heated to reflux. The MeOH is evaporated in vacuo, and the aqueous residue diluted with more H2O, and acidified with 0.IN HCl to pH between 6°-7 while contained in an ice-bath. An orange solid precipitates. This is collected, washed with ether then dried under vacuum (0.1 mm at 22° C.) for a few hours to obtain 2-(indol-3-yl)-4-carboxy-6,7-dimethoxyquinoline m.p. 286° C. dec).
