Reaktionsschritte

The title compound of Example 1 (9.8 g, 55.3 mmol) and 2-bromo-4-fluorobenzonitrile (13.27 g, 66.4 mmol) were dissolved in anhydrous dimethylformamide (DMF, 300 mL). To this was added sodium hydride (95%, 2.79 g, 111 mmol) and the reaction was stirred at 55° C. for 1 hour. The reaction mixture was cooled to room temperature and water was added. A tan solid precipitated which was filtered, washed with water and ether and then dried in vacuo (16.5 g, 84%). LCMS m/z: (M+H)=358.1.
