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.
