Procedure
A mixture of 22.8 g of Intermediate XIX and 6.8 g of sodium azide in 110 ml of dimethylformamide was stirred for 3 hours at 100° C. After cooling to ambient temperature, 130 ml of water and 88 ml of ethanol were added to the reaction mixture. After 1 hour, the crystals were collected by vacuum filtration, washed with water, and desiccated. Yield: 22 g of the title product. A sample recrystallized from ethanol had a melting point of 132°-134° C.
