Procedure

A mixture of the compound of Example 35 (3.95 g, 0.015 mol) and sodium carbonate (1.58 g, 0.015 mole) in 40 ml methanol can be stirred at reflux for 6 hours. On cooling, the mixture can be poured into water and the precipitate collected by suction filtration. Recrystallization of the solid from ethanol can give the pure title compound.
