実験手順

To a suspension of (1-isopentyl-5-(trifluoromethyl)-1H-imidazo[4,5-b]pyridin-2-yl)methanol 44-3 (1.0 g, 3.5 mmol (73% purity)), 1-cyclopropyl-1H-imidazo[4,5-c]pyridin-2(3H)-one 10-d (731.8 mg, 4.2 mmol) and triphenylphosphine (1.1 g, 4.2 mmol) in 24 ml dry THF was added (E)-diisopropyl diazene-1,2-dicarboxylate (1.0 ml, 5.2 mmol) at room temperature. The reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was evaporated to dryness and purified by preparative column chromatography to obtain 44 as a white solid (578.0 mg, 37%). m/z=445 (M+H)+. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.02 (m, J=6.50 Hz, 8H) 1.13-1.24 (m, 2 H) 1.48-1.64 (m, 2 H) 1.73 (dquin, J=13.19, 6.49, 6.49, 6.49, 6.49 Hz, 1 H) 2.92 (tt, J=6.81, 3.48 Hz, 1 H) 4.35-4.52 (m, 2 H) 5.41 (s, 2 H) 7.13 (d, J=5.27 Hz, 1 H) 7.61 (d, J=8.28 Hz, 1 H) 7.79 (d, J=8.28 Hz, 1 H) 8.34 (d, J=5.27 Hz, 1 H) 8.68 (s, 1 H).
