Versuchsvorschrift

To a suspension of sodium 4-hydroxybenzenesulfonate (1.3 g, 5.6 mmol) in iso-propanol (20 ml) was added product from Example 8 (700 mg, 6.8 mmol) followed by 1N sodium hydroxide (6.1 ml, 6.1 mmol) and the resulting mixture was heated at 65-70° C. for 15 hours. The reaction mixture was concentrated in vacuo, the solid collected and washed with diethy ether to give 880 mg (53%) of the product as a solid.
