Procedure

0.292 ml (3.78 mmol) of mesyl chloride is added to a solution of 350 mg (1.08 mmol) of the compound of Example 29 in 3 ml of pyridine, and the medium is stirred at room temperature for 4 hours. The reaction medium is concentrated under reduced pressure. The residue is taken up in 1 N hydrochloric acid and extracted with dichloromethane. The organic phase is separated after settling out, washed with a saturated aqueous sodium chloride solution, dried over sodium sulphate and concentrated under reduced pressure. The residue is crystallized from ethanol. 327 mg of yellow crystals are obtained.
