Reaction Steps

Ethyl 3-(5-(2-formyl-3,5-bis(trifluoromethyl)phenyl)picolinamido)propanoate (76 mg, 0.16 mmol) and 4′-chloro-[1,1′-biphenyl]-4-amine (40 mg, 0.20 mmol) in DMSO (0.16 mL) was stirred at 100° C. After 30 min EtOH (0.16 mL) was added and the resulting homogeneous solution was stirred at 100° C. After 1 h the resulting homogeneous solution was cooled to room temperature, and NaBH4 (20 mg, 0.53 mmol), EtOH (1 mL), and DMSO (0.5 mL) were added and the resulting mixture was stirred. After 30 min, additional NaBH4 (20 mg, 0.53 mmol) was added and the resulting homogeneous solution was stirred. After 20 min the resulting mixture was diluted with DCM (5 mL) and 1 M NaH2PO4 (4 mL) was carefully added. Water was added and the aqueous phase was extracted with DCM. The combined organic layers were dried (Na2SO4), concentrated, and purified via column chromatography to yield the title compound.
