Versuchsvorschrift

DIPEA (96 μL, 0.55 mmol) was added to a mixture of 6-chloro-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 32.1, 117 mg, 0.25 mmol) and (tert-butyl 3-azabicyclo[3.1.0]hexan-1-ylcarbamate, 59.2 mg, 1.2 mmol) in iPrOH (250 μL) in a vial, which was sealed and the RM mixture was stirred at 140° C. for 18 h. After cooling at 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 residue which was dissolved in DCM (1 mL), cooled to 0° C., treated with TFA (0.45 mL, 5.85 mmol) and was stirred at RT for 3 h. The RM was poured into 10% aq. Na2CO3 (10 mL) and extracted with EtOAc. The combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a crude product which was purified by preparative SFC (Column 2-EP, from 22% to 27% in 6 min) to afford the title compound as an amorphous white powder.
