Temperature: 200 °C

Procedure

To a 5 mL, microwave vial containing 7-(6-chloro-pyrimidin-4-yloxy)-quinoline, (Example 102(a)), (0.30 g, 1.2 mmol) and ethylene glycol dimethyl ether (2 mL) was added 3-diethyl (3-pyridyl)borane (0.21 g, 1.5 mmol, Aldrich), 1 N sodium carbonate (1.8 mL), and palladium(0)-tetrakis-triphenylphosphine (0.14 g, 0.15 mmol, Strem Chemical). The vial was sealed and heated at 200° C. for 20 min in a microwave synthesizer, allowed to cool to room temperature, and the reaction mixture was diluted with 1 N sodium hydroxide (25 mL) and extracted with dichloromethane (2×50 mL). The organic layers were combined, dried over Na2SO4, filtered and concentrated onto silica gel. The crude material was purified by silica gel chromatography (gradient: 1–2% 2 N ammonia in methanolvdichloromethane) to obtain the title compound as an off-white solid. Mp: 155–158° C. MS (ESI, pos. ion.) m/z: 301 (M+1).
