Participants

Reaction Steps

Following the procedures for Example 141, tert-butyl 4-((4-amino-1-methyl-1H-pyrazol-5-yloxy)methyl)piperidine-1-carboxylate and 3-amino-6-bromopicolinic acid were reacted to give 3-amino-6-bromo-N-(1-methyl-5-(piperidin-4-ylmethoxy)-1H-pyrazol-4-yl)picolinamide, which was reacted with 2-fluorophenylboronic acid under palladium catalyzed Suzuki conditions to give 117 as a white solid (6.7 mg, 7.2%) over three steps. 1H NMR (400 MHz, DMSO) δ 9.66 (s, 1H), 8.10 (t, J=7.2, 1H), 7.71 (dt, J=37.9, 19.0, 1H), 7.60-7.25 (m, 5H), 7.03 (s, 2H), 3.97 (d, J=6.2, 2H), 3.72-3.42 (m, 3H), 2.76 (t, J=31.9, 2H), 2.36 (t, J=12.2, 2H), 1.88-1.53 (m, 3H), 1.25-0.99 (m, 2H).
