Under a positive flow of argon while stirring, surfactant solution (1.0 mL, 2 wt % TPGS-M-PEG-750 in water), and Et3N (0.21 mL, 1.5 mmol) were added by syringe and stirred vigorously for 2 h. The reaction mixture was then diluted with brine and extracted with EtOAc. The solution obtained was dried over anhydrous MgSO4 and concentrated by rotary evaporation. The residue was purified by flash column chromatography eluting with 20% CH2Cl2/hexanes to afford the product (83 mg, 93%) as a slightly yellow oil.
