DIPEA (0.182 mL, 1.043 mmol) was added to 6-chloro-5-(1H-pyrazol-5-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 38.1, 70 mg, 0.174 mmol), N,N-dimethylazetidin-3-amine (60.1 mg, 0.348 mmol) and iPr2O (1 mL) in a vial, which was sealed and the RM was stirred at 110° C. for 5 h. After cooling to RT, the RM was dissolved in EtOAc, washed with brine, dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a crude product which was purified by preparative HPLC (Condition 10). Fractions containing product were combined, treated with sat. aq. Na2CO3 and the MeCN was evaporated off under reduced pressure. The aq. phase was extracted with DCM (2×20 mL) and the combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the title compound as white crystals.
