Procedure

The operation is carried out as in Stage 1 of Example 10 starting from 280 mg of the product obtained in Stage 1 of Example 7, 3 ml of methylene chloride, 0.17 ml of triethylamine and 0.128 ml of 4-fluorobenzenesulphonic acid chloride in place of the 4-methyl-benzenesulphonic acid chloride then the reaction medium is agitated at ambient temperature for approximately 30 min. Then 2 ml of water is added, followed by extracting with 3×5 ml of methylene chloride, washing with 5 ml of saturated sodium chloride, drying, evaporating, impasting in 5 ml of ether then in 5 ml of pentane, separating and drying. In this way 360 mg of expected product is obtained.
