Reaction Conditions

Reaction Steps

To 84A (9.8 g, 45 mmol) in trifluoroacetic acid (20 mL) was added triethylsilane (14.3 mL, 90 mmol). After stirring at 50° C. for 6 h, the reaction was quenched with 100 mL of saturated NaHCO3 solution and extracted with diethyl ether (3×). The combined organic layers were washed with brine, dried over MgSO4, and concentrated. The resulting residue was distilled at 200° C. to give 84B (85% purity).
