Reaction Steps

9-Oxo-9H-indeno[2,1-c]pyridine-7-carboxylic acid was obtained by allowing 4-pyridin-4-ylphthalic acid [FAB: 244 (M+H)+] which had been synthesized by carrying out the same operations of Reference Examples 27 and 28 using 4-bromoisophthalic acid diethyl ester and 4-pyridine boronic acid to undergo the reaction with lithium 2,2,6,6-tetramethylpiperidide at 0° C. in THF. By carrying out reaction of this compound by the same method of Reference Example 30, ethyl 9-oxo-9H-indeno[2,1-c]pyridine-7-carboxylate was obtained. FAB: 254 (M+H)+.
