Procedure

A mixture of Example 224a (0.075 g, 0.125 mmol), propargyl alcohol (0.018 mL, 0.313 mmol), di-tert-butyl azodicarboxylate (0.072 g, 0.313 mmol), and triphenylphosphine (3 mmol/1 g)-polymer supported (0.105 g, 0.4 mmol) in THF (3.0 mL) was stirred at room temperature overnight. The reaction mixture was diluted with EtOAc and dichloromethane, filtered through celite, concentrated and purified on 12 g column, using Analogix System, eluted with 0-30% EtOAc in hexanes to give 56.0 mg (70%) of the title compound.
