Participants

Reaction Steps

Prepared analogously to Compound 3C using 3-amino-N-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-carboxamide (Compound 48D, 284 mg, 1.03 mmol) and 3-(4-bromo-5-chloro-1H-pyrazol-1-yl)propan-1-ol (Compound 49D, 270 mg, 1.1 mmol) to afford 151 mg of the title compound (48%). 1H NMR (400 MHz, CD3OD) δ 8.12 (s, 1H), 7.67 (d, J=8.6 Hz, 1H), 7.20 (d, J=8.6 Hz, 1H), 4.32 (t, J=7.1 Hz, 2H), 3.60 (t, J=6.1 Hz, 2H), 2.94 (s, 3H), 2.06 (quin, J=6.6 Hz, 2H). MS (ESI): m/z=310.20/312.18 [M+H]+. UPLC: tR=0.77 min (UPLC-TOF: polar—2 min).
