2′-Fluoro-5′-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)[1,1′-biphenyl]-2-carbonitrile → 2'-Fluoro-5'-(7-isopropylimidazo[1,2-alpha]pyrimidin-3-yl)biphenyl-2-carbonitrile

Participants

Reaction Steps

3-Bromo-7-isopropylimidazo[1,2-α]pyrimidine was coupled with 2′-fluoro-5′-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)biphenyl-2-carbonitrile as described in Example 1 to give 2′-fluoro-5′-(7-isopropylimidazo[1,2-α]pyrimidin-3-yl)biphenyl-2-carbonitrile as an off-white powder: δH (360 MHz, CDCl3) 1.38 (6H, d, J 7), 3.15 (1H, septet, J 7), 6.87 (1H, d, J 7), 7.39 (1H, t, J 9), 7.52-7.63 (4H, m), 7.71 (1H, dd, J 8 and 1), 7.83 (2H, dd, J 8 and 7), 8.74 (1H, d, J 7); m/z (ES+) 357 (M++H).
