Reaction Steps

To a suspension of Example 75A (1.6 g, 10 mmol) and N,O-dimethylhydroxylamine (1.1 g, 11 mmol) in dichloromethane (40 mL) and dimethylformamide (10 mL) was added triethylamine (1.67 mL, 12 mmol) and EDC (2.1 g, 11 mmol), and the mixture was stirred at room temperature for 24 hours. The solvents were evaporated under reduced pressure, and the resulting residue was diluted with ethyl acetate and washed with water. The organic layer was dried over sodium sulfate and purified by silica gel column chromatography in ethyl acetate to afford the title compound. MS (ESI+) m/z 206.0 (M+H)+.
