Procedure
To a 500 mL round bottom flask containing 131 (5.9 g, 17.38 mmol) and azido acid (2.13 g, 20.8 mmol) in THF (174 mL) was treated with EDC (5.33 g, 27.81 mmol), HOBt (3.75 g, 27.81 mmol) and TEA (12.2 mL, 86.9 mmol) at room temperature and was stirred for 12 h. The reaction was concentrated on silica and was purified over silica gel using EtOAc:Hexanes (1:1) as an eluent to afford 132 (6.5 g, 89%) as a colorless oil.
