Versuchsvorschrift

A mixture of methyl 2-methyl-5-morpholino-3H-imidazo[4,5-b]pyridine-7-carboxylate (138 mg, 0.5 mmol), 1-(bromomethyl)naphthalene (166 mg, 0.75 mmol) and Na2CO3 (138 mg, 1 mmol) in DMF (10 mL) was stirred at 80° C. for 5 h. It was cooled to room temperature and poured into water (50 mL). It was extracted with EA (100 mL×2). The combined organic layers were washed with brine (100 mL×2), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by chromatography on silica gel eluted with 100% EA to afford the desired product as a black solid (143 mg, 69%); LC/MS: MS (ES+) m/e 417 (MH+); 1H NMR (300 MHz, DMSO-d6) δ ppm 2.42 (s, 3H), 3.42 (t, J=4.5 Hz, 4H), 3.67 (t, J=4.5 Hz, 4H), 3.93 (s, 3H), 5.92 (s, 2H), 6.70 (d, J=7.2 Hz, 1H), 7.09 (s, 1H), 7.39 (t, J=7.5 Hz, 1H), 7.57-7.65 (m, 2H), 7.87 (d, J=9.0 Hz, 1H), 7.90 (d, J=9.0 Hz, 1H), 8.34 (d, J=7.2 Hz, 1H).
