Reaction Steps
The ester of Example 19 (50 mg) was suspended in a 1 N solution of hydrochloric acid in 1:1 aqueous methanol and this was heated for one hour on the steam bath. The excess solvent was removed by concentration on a hot plate and the suspension cooled and filtered to give 48 mg of 2,5,7,12-tetrahydroxy-1,2,3,4,6,11-hexahydro-6,11-dioxonaphthacene (formula 17) as a red powder.
