Reaction Steps

To a solution of n-BuLi (1.6 M in hexanes) (290 μl, 0.465 mmol) in THF (1 ml) was added a solution of CH3CN (19.1 mg, 0.465 mmol) in THF (2 ml) dropwise at 0° C. The mixture was stirred for 20 min, then a solution of 406D (62 mg, 0.221 mmol) in THF (5 ml) was added. After the mixture was stirred for 40 min, the reaction temperature was lowered to −78° C., AcOH (38 μl, 0.663 mmol) was added. The reaction mixture was then stirred at rt overnight. Solvent was removed, 406E (26 mg, 50%) was obtained as a yellowish solid after preparative HPLC purification. LCMS Found: (M+H)+=232.
