Reaktionsschritte
To a solution of sodium hydride (60% dispersion in mineral oil, 46 mg, 1.2 mmol) in N,N-dimethylformamide (4.6 mL) at 0° C. was added a solution of the title compound from Example 22 Step C (100 mg, 0.463 mmol) in N,N-dimethylformamide (4.6 mL). After warming to room temperature and stirring for 1 hour, the solution was cooled back to 0° C. and iodomethane (35 μl, 0.56 mmol) was added. After stirring overnight, the reaction was poured into water and extracted with ethyl acetate. The organic extracts were combined, washed with saturated aqueous sodium chloride solution, dried over sodium sulfate and concentrated under reduced pressure to afford the title compound: LCMS m/z 232.97 [M+H]+.
