Reaktionsschritte

A mixture of 2-azido-quinolin-8-ol (0.28 g, 1.5 mmol), 2-chloro-4-(4-trifluoromethyl-phenyl)-pyridine (Example 410 (c), 0.26 g, 1 mmol), and sodium hydride (64 mg, 1.6 mmol) in DMF (2 mL) was heated in a 180° C. oil bath for 48 h. The reaction mixture was then transferred to a 5-mL tube, and irradiated in the Microwave Smith Synthesizer at 250° C. for 10 min. EtOAc and brine were added, and the aqueous layer was extracted with EtOAc. Combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The compound was purified on a Biotage 40S column (98:2 dichloromethane:MeOH) followed by recrystallization from EtOAc/hexanes to give the title compound as a light-yellow shiny crystal. MS (ESI, pos. ion) m/z: 382 (M+1). Mp: 196.5-199.5° C. Anal. Calcd for C21H14F3N3O: C, 66.14; H, 3.70; N, 11.02. Found: C, 66.18; H, 3.69; N, 11.08.
