Participants

Reaction Steps

A solution of [5-(5-amino-2-fluoro-phenyl)-5-trifluoromethyl-2,5,6,7-tetrahydro-[1,4]oxazepin-3-yl]-carbamic acid tert-butyl ester (50 mg, 0.128 mmol), 5-cyano-2-pyridinecarboxylic acid (28.4 mg, 0.192 mmol) and HOAT (31.3 mg, 0.230 mmol) in 0.5 mL DMF was cooled to 0-5° C. EDC (36.7 mg, 0.192 mmol) and DIPEA (33 mg, 0.256 mmol) were added. The resulting solution was allowed to warm up to rt over night. The reaction mixture was then partitioned between saturated aqueous NaHCO3 solution and EtOAc. The layers were washed with saturated aqueous NaHCO3 solution, brine and EtOAc. The combined organic layers were dried over MgSO4.H2O and evaporated. The crude product was purified on a silica gel column by eluting with hexane/EtOAc 4/1→3/1 to give 63.3 mg of the title compound as a white solid.
