Reaktionsschritte

To a solution of 8-methyl-2-phenylquinoline-3-carboxaldehyde (80 mg, 0.32 mmol) in THF (5 mL) was added di-n-butyltin dichloride (10 mg, 0.032 mmol), phenylsilane (70 mg, 0.64 mmol) and 6-aminoquinoxaline (46 mg, 0.32 mmol). The mixture was heated in a microwave at 100° C. for 3 h. Purification by preparative HPLC (Method 2) gave the title compound as an off-white solid (45 mg, 37%). δH (CDCl3) 8.61 (d, J 2.1 Hz, 1H), 8.51 (d, J 1.9 Hz, 1H), 8.24 (s, 1H), 7.84 (d, J 9.0 Hz, 1H), 7.71-7.76 (m, 1H), 7.61-7.66 (m, 1H), 7.40-7.58 (m, 6H), 7.10 (dd, J 9.2, 2.6 Hz, 1H), 6.88 (d, J 2.6 Hz, 1H), 4.64-4.69 (m, 2H), 4.52-4.60 (m, 1H), 2.82 (s, 3H). LCMS (ES+) 377.2 (M+H)+, RT 4.23 minutes (Method 4).
