Reaction Steps

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 tert-butyl 4,7-diazaspiro[2.5]octane-4-carboxylate to afford an off-white powder. HPLC (Condition 4) tR=4.44 min, UPLC-MS (Condition 3) tR=0.81 min, m/z=475 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 0.27-0.54 (m, 4H) 2.82 (br. s, 2H) 2.96-3.20 (m, 5H) 6.64 (br. s, 1H) 7.32 (d, J=8.21 Hz, 2H) 7.86 (d, J=8.99 Hz, 3H) 8.29 (br. s, 1H) 8.71 (br. s, 1H) 10.37 (br. s, 1H) 13.00 (br. s, 1H).
