Procedure
6-Chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1H-pyrazol-5-yl)nicotinamide (Stage 48.1, 500 mg, 1.253 mmol), 4-aminobutane-1,3-diol (Stage 97.1, 152 mg, 1.447 mmol), DIPEA (0.667 mL, 3.82 mmol) and iPrOH (2 mL) were added to a MW vial, which was sealed, flushed with argon and stirred at 130° C. for 20 h. The RM was diluted with EtOAc and washed with water and brine, dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a residue which was treated with iPr2O and the resulting solid was filtered off and purified by flash chromatography (Silica gel column, 40 g, DCM/DCM-MeOH (9:1)) to afford the title compound as a white solid. UPLC-MS (Condition 8) tR=0.94 min, m/z=468 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1H NMR (400 MHz, DMSO-d6) δ ppm 1.46-1.74 (m, 2H) 3.44-3.58 (m, 3H) 3.64-3.72 (m, 1H) 3.77-3.90 (m, 1H) 4.40 (t, J=5.07 Hz, 1H) 4.82 (d, J=5.38 Hz, 1H) 6.96 (t, J=1.96 Hz, 1H) 7.36 (d, J=8.93 Hz, 2H) 7.83-7.99 (m, 3H) 8.41 (d, J=2.32 Hz, 1H) 8.65 (d, J=2.20 Hz, 1H) 9.04 (s, 1H) 10.21 (s, 1H) 13.21 (s, 1H).
