Reaction Steps

1-(2-Chloro-3,6-difluorobenzyl)-7-iodo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazine (100 mg) was reacted with 2-(4-morpholino)pyridine-5-boronic acid pinacol ester as in General Procedure 4A to give the title compound as a beige foam (52% yield). M.p. (foam), LCMS: m/z=458.04 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 3.28-3.34 (m, 2H), 3.51-3.59 (m, 6H), 3.81-3.88 (m, 4H), 4.54 (s, 2H), 5.30 (s, 1H), 6.69 (d, J=8.8 Hz, 1H), 7.00-7.08 (m, 2H), 7.11-7.18 (m, 1H), 7.53 (s, 1H), 7.61 (dd, J=8.8 Hz, 2.5 Hz, 1H), 8.33 (s, J=2.2 Hz, 1H).
