Procedure
A mixture consisting of the product obtained in example 38, in 5 ml of a 7 M solution of ammonia in methanol, is stirred at ambient temperature for 3 hours. The reaction mixture is concentrated under reduced pressure and the crude product obtained is purified by silica gel chromatography, elution being carried out with a dichloromethane/methanol mixture (97/3; v/v). The product obtained is washed with cold water and then filtered and dried. The desired product is obtained in the form of a white solid with a yield of 36%.
