Versuchsvorschrift
Following Example 121c, 264a (0.58 g, 1.25 mmol), trifluoroacetic acid (0.96 mL, 12.5 mmol) and methylene chloride (20 mL) were reacted. Work-up and concentrated to afford a quantitative yield of 264b (454 mg) as yellow oil, which was used without purification in the next step. MS (ESI+) m/z 365.2 (M+H).
