Procedure

To a solution of 149 (764.1 mg, 1.894 mmol) in THF (18.9 ml) 78° C. was added drop-wise a solution of methyl magnesium bromide (1.579 ml, 4.74 mmol). The temperature was allowed to slowly warm to 0° C. and the reaction was stirred an additional hour at 0° C., then it was quenched with water and extracted with EtOAc. The organic layer was dried over Na2SO4 and concentrated and the residue was purified by chromatography (Biotage, 20 to 70% EtOAc in hexane) to afford 153 (646 mg, 1.54 mmol, 87%) as peach oil. LRMS (ESI): (calc.) 419.2 (found) 442.2 (MNa)+.
