Versuchsvorschrift

0.47 g of potassium carbonate and 1.7 g of 3-amino-1-propanol are successively added to a solution of 0.55 g of 4-{4-[5-(benzyloxy)pyridin-3-yl]-9H-carbazol-9-yl}-2-fluorobenzonitrile, obtained in stage 3 of Example 67, in 6 ml of dimethyl sulphoxide. The reaction mixture is heated at 90° C. for 1 hour 20 minutes in a microwave, and then 11.5 ml of ethanol are added, followed by 2.2 ml of a 1N solution of sodium hydroxide and 2.2 ml of 30% aqueous hydrogen peroxide. The reaction mixture is stirred at ambient temperature for 1 hour and then diluted with distilled water. The aqueous phase is extracted twice with ethyl acetate and the combined organic phases are washed with water and a saturated solution of sodium chloride, dried over magnesium sulphate and concentrated under reduced pressure, and the residue is triturated with dichloromethane and diisopropyl ether, so as to give 0.29 g of 4-{4-[5-(benzyloxy)pyridin-3-yl]-9H-carbazol-9-yl}-2-[(3-hydroxypropyl)amino]benzamide in the form of a white solid, the characteristics of which are the following:
