Versuchsvorschrift

0.9 g of potassium carbonate and 3.3 ml of 3-amino-1-propanol are successively added to a solution of 1 g of 2-methylpropan-2-yl 4-[4-(6-cyanopyridin-3-yl)-9H-carbazol-9-yl]-2-fluorobenzoate, obtained in stage 1 of Example 49, in 8 ml of dimethyl sulphoxide. The reaction mixture is heated at 90° C. for 1 and a half hours in a microwave, and then diluted with distilled water. The aqueous phase is washed 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 filtered. The residue is purified by silica gel chromatography, elution being carried out with a mixture of cyclohexane and ethyl acetate (70/30 by volume), so as to give 0.7 g of 2-methylpropan-2-yl 4-[4-(6-cyanopyridin-3-yl)-9H-carbazol-9-yl]-2-[(3-hydroxypropyl)-amino]benzoate in the form of a yellow oil, the characteristics of which are the following:
