Participants

Reaction Steps

The title compound was prepared in a similar manner to that described in Example 14 using hydroxylamine hydrochloride (77 mg, 1.11 mmol) and 3′-(7-formylimidazo[1,2-α]pyridin-3-yl)biphenyl-2-carbonitrile (120 mg, 0.37 mmol) to afford a white crystalline solid (105 mg, 83%), essentially as a single geometric isomer. 1H NMR (400 MHz, d6-DMSO) δH 7.27 (1H, dd, J 1 and 7), 7.61-7.90 (8H, m), 7.90 (2H, s), 8.00 (1H, dd, J 8 and 1), 8.25 (1H, s), 8.68 (1H, d, J 7), 11.53 (1H, s); m/z (ES+) 339 (M++H).
