Procedure

The operation is carried out as in Stage 2 of Example 5 starting from 160 mg of the product obtained in Stage 1 of Example 5, 3 ml of butanol and using 0.081 ml of 4-(trifluoromethoxy)-benzenamine in place of the benzylamine and the reaction medium is taken to a temperature of approximately 80 to 85° C. for approximately 20 hours, left to return to ambient temperature, diluted with 3 ml of isopropanol, placed for approximately one hour at a temperature of approximately 0° C., followed by separating, washing with 5 ml of isopropanol and drying under vacuum at a temperature of approximately 50° C. After purification on silica eluting with methylene chloride/ ethyl acetate in a proportion of 90/10, 203 mg of expected product is obtained in the form of white crystals.
