Procedure

To a solution of the compound (76.0 mg, 162 μmol) of Example 42 in ethanol. (2 ml) were added 1 mol/L aqueous solution of lithium hydroxide (567 μl, 567 μmol) and water (1 ml), and the mixture was stirred for 75 minutes at 50° C. After cooling, water was added to the reaction mixture and the insolubles were filtered off. The filtrate was brought to pH4 with 3 mol/L hydrochloric acid. The precipitated crystals were collected by filtration, washed with water, and then air-dried, thereby obtaining 27.5 mg of title compound as light brown powder. Yield 39%.
