Procedure
To the product from Example 170c in toluene (25 mL) was added diphenylphosphoryl azide (1.72 g, 6.23 mmol), followed by 1,8-diazabicyclo[4.3.0]undec-7-ene (0.95 g, 6.2 mmol). The mixture was stirred at 25° C. for 18 h. The reaction was poured into water and extracted with ethyl acetate. The combined organic layers were washed with water, brine, dried over sodium sulfate, filtered and concentrated under vacuum giving the title compound. The crude product was purified on silica gel, eluting with hexanes/ethyl acetate/methanol (85:17:3) to provide the title compound (700 mg, 50%).
