Reaction Steps

DIPEA (73 μL, 0.42 mmol) was added to a solution of 5-bromo-6-chloro-N-(4-((trifluoromethyl)thio)phenyl)nicotinamide (Stage 11.2, 123 mg, 0.3 mmol) and (R)-pyrrolidin-3-ol (31.4 mg, 0.36 mmol) in iPrOH (300 μL) in a vial, which was sealed and heated at 140° C. for 1 h. After cooling at RT, the RM was diluted with EtOAc, washed with brine, dried over Na2SO4 and the solvent evaporated off under reduced pressure to give a residue which was triturated with iPr2O, filtered and dried to afford the title compound as a white crystalline powder. HPLC (Condition 4) tR=5.9 min, UPLC-MS (Condition 3) tR=1.21 min, m/z=464.1 [M+H]+.
