Reaction Steps

To compound 27 (50 mg, 0.12 mmol ) in anhydrous ether (0.63 mL) at -78° C. under argon was added n-BuLi (1.6M in hexanes, 0.12 mL, 0.19 mmol) and the mixture was stirred at -78° C. (20 minutes). A solution of ethyl formate, 1M in ether (0.25 mmol, 2 eq.) was added and the mixture stirred (0.5 hours at -78° C.). Saturated aqueous NH4Cl (1 mL) was added and the mixture warmed to ambient temperature and extracted with ether (3×1 mL). The combined extracts were dried (MgSO4) and taken to dryness under reduced pressure, affording 43 mg of crude 28, however, contaminated with starting material 27.
