Trifluoroacetic acid → HCID 44271005, compound

Participants

Reaction Steps

To a solution of 0.700 g (1.136 mmol) of the product of Example 33 and 0.363 mL (2.273 mmol) of triethylsilane dissolved in 10 mL of dichloromethane was dropwise added 10 mL of trifluoroacetic acid. The reaction mixture was stirred at room temperature for 0.5 h and then concentrated in vacuo. The residue was chromatographed on silica gel eluting with EtOAc/Hexanes (gradient: 1:3-1:1) to provide 0.263 g (62%) of the desired product as a colorless oil. Electrospray Mass Spec: 375.4 (M+H)+.
