The title compound was prepared in an analogous fashion to that described in Example 8 using (R)-3-bromo-N-(4-(chlorodifluoromethoxy)phenyl)-4-(3-hydroxypyrrolidin-1-yl)benzamide (Stage 20.1) and 1-(Tetrahydro-2H-pyran-2-yl)-1H-pyrazole-5-boronic acid pinacol ester to afford an off-white solid. UPLC-MS (Condition 3) tR=0.99 min, m/z=449.0 [M+H]+, m/z=493.0 [M+formic acid-H]−; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.67-1.79 (m, 1H) 1.80-1.92 (m, 1H) 2.72 (d, J=10.88 Hz, 1H) 3.03-3.18 (m, 2H) 3.19-3.30 (m, 1H) 4.19 (br. s, 1H) 4.77-4.92 (m, 1H) 6.22-6.42 (m, 1H) 6.76-6.93 (m, 1H) 7.31 (d, J=8.56 Hz, 2H) 7.45-7.81 (m, 1H) 7.83-7.95 (m, 4H) 10.12 (s, 1H) 12.71-13.12 (m, 1H).
