실험 절차

Treatment of a mixture of ethyl 5-iodo-7-methyl-4-oxo-1,4-dihydroquinoline-2-carboxylate and ethyl 7-iodo-5-methyl-4-oxo-1,4-dihydroquinoline-2-carboxylate (0.449 g) with sodium hydroxide (0.20 g) as described in Example 1c gave a mixture of the corresponding carboxylic acids. Chromatography of this mixture (0.220 g) on a reverse phase carbon-18 column gave 5-iodo-7-methyl-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (12 mg), mp 306° C. δ (360 MHz, DMSO-d6) 2.33 (3H, s, CH3), 6.55 (1H, s, 3-H) and 7.75 (2H, bs, 6-H and 8-H).
