実験手順

To methyl acridine-4-carboxylate, prepared in Example 4,(183 mg), was added a degassed solution of NaOH in aqueous EtOH (1:1,2M)(35 ml). The mixture was stirred for 3 hours at 50° C., when a clear solution was obtained, then neutralised with glacial AcOH. Extraction with EtOAc (3×15 50 ml) followed by chromatography on silica gel, eluting with EtOAc/petroleum ether (1:4), gave acridine-4-carboxylic acid (160 mg, 87%), mp (Me2CO) 196-197° C. (lit, mp 202-204° C.).
