Versuchsvorschrift

To a solution of Intermediate 92a (667 mg, 2.83 mmol) and Et3N (630 μL, 4.53 mmol) in DCM (5 mL) was added triisopropylsilyltrifluoromethane sulfonate (950 μL, 3.54 mmol) and the mixture was stirred at RT for 1 h. The mixture was washed with sat. sodium hydrogen carbonate solution then brine, dried and concentrated in vacuo. The residue was purified by FCC, 2-6% MeOH in DCM, to give the title compound as a pale green viscous oil (1.11 g, quant.). LCMS (Method 3): Rt 4.76 min, m/z 393 [MH+].
