To a solution of tri-methylsulfoxonium iodide (495 mg, 2.25 mmol) in DMSO (4 mL) was added NaH (90 mg, 2.2 mmol) and the resulting mixture was stirred for 30 min. At this time compound 79a (400 mg, 1.87 mmol) was added in one portion and the resulting mixture was stirred overnight. The reaction mixture was then diluted with EtOAc (100 mL), washed with saturated sodium bicarbonate (100 mL) and concentrated in vacuo to obtain a residue which was purified by flash column chromatography on silica gel (0-50% EtOAc-heptane) to afford compound 79b as a white solid. Mass spectrum (LCMS, ESI pos.) Calcd. For C14H13NO2 228.0 (M+H). found 228.2.
