Procedure
In a flask protected by a safety screen, a solution of the product of step B (12.27 g, 0.042 mmol) and lithium azide (2.47 g, 0.051 mmol) in DMF (30 ml) was stirred at 45° C. for 18 hr. The solvent was evaporated in vacuo and the residue triturated with EtOAc (100 ml) and filtered. The filtrate was evaporated in vacuo and the residue dissolved in MeOH (255 ml) which was saturated with gaseous ammonia at 0° C. and then stirred at room temperature for 72 hr. The solvent was removed by distillation in vacuo to afford the title compound as an oil.
