Procedure

A mixture of 15.2 g of Intermediate XI and 6.24 g of sodium azide in 150 ml of anhydrous dimethylformamide was stirred at 70°-75° C. for 12 hours. After cooling to 20°-25° C., the reaction mixture was poured into 1.5 liters of water and extracted with dichloromethane. The organic solution was washed with aqueous sodium chloride solution and dried on anhydrous sodium sulfate. The solvents were evaporated off in vacuo. The residue was taken up in water, collected by suction filtration and dried to give 14 g of the title compound, m.p. 119°-120° C.
