Procedure

The title compound was prepared in an analogous fashion to that described in Example 33 using 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)nicotinamide (Stage 48.2) and 1-(2-fluoroethyl)piperazine to afford an off-white powder. HPLC (Condition 4) tR=4.57 min, UPLC-MS (Condition 3) tR=0.82 min, m/z=492.9 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.54-2.71 (m, 2H) 3.09-3.21 (m, 4H) 3.24-3.35 (m, 4H) 4.46 (t, J=4.89 Hz, 1H) 4.58 (t, J=4.89 Hz, 1H) 6.66 (br. s, 1H) 7.33 (d, J=8.60 Hz, 2H) 7.86 (d, J=8.99 Hz, 3H) 8.28-8.37 (m, 1H) 8.73 (d, J=1.95 Hz, 1H) 10.39 (br. s, 1H) 12.96-13.11 (m, 1H).
