実験手順

A mixture of 4,7-dihydro-4,7-dioxo-6-propoxy-1-propyl-1H-cyclohepta[b]pyridine-2-carboxlic acid ethyl ester (3.8 g, described in Example 22) and 19% hydrochloric acid (113 ml) is refluxed for 30 minutes. Charcoal is added and the hot mixture is filtered. The filtrate is cooled to room temperature and the crystalline precipitate is collected and dried to obtain the title compound, mp > 250° C.
