To a solution of the compound of Example 139 (2.2 g, 4.0 mmol) in ethanol (100 ml) was added aqueous solution of NaOH (2.0 g, 50 mmol, 12.5 eq.) and the mixture was heated at 100° C. for 4 h. The mixture was quenched and extracted as in Example 1(d). The solvent was distilled off to afford the product in 90% yield (1.8 g).
