実験手順

A solution of 4,5-dihydro-6-oxa-1-thia-3-aza-benzo[e]azulene-2-carboxylic acid ethyl ester (1 eq, 1.9 mmol, 530 mg), and sodium hydroxide (5 eq, 9.6 mmol, 385 mg), in THF (5 ml) and water (5 ml) was allowed to stir at RT for 3 hrs. Reaction concentrated in vacuo and the solid washed with water to give 4,5-dihydro-6-oxa-1-thia-3-aza-benzo[e]azulene-2-carboxylic acid (290 mg, yield 58%).
