실험 절차

A yellow solution of 1-(2-amino-5-bromophenyl)-2,2,2-trifluoroethanone (1.32 g, 4.94 mmol, Intermediate 8, step b) and 1,1,1-trifluoro-3-phenylpropan-2-one (0.980 g, 5.21 mmol) in DMF (4.95 mL) was treated with tributylamine (1.23 mL, 5.19 mmol) and stirred at 130° C. under air (capped) for 2 hours. The homogeneous orange solution was then cooled to room temperature and partitioned with ether (8 mL) and 1 M NaH2PO4 (8 mL). The organic layer was washed with 1 M NaH2PO4 (1×8 mL), dried (Na2SO4), filtered, and concentrated, and the residue was flash chromatographed with a heptane to 30% DCM/heptane gradient to yield the title compound as a nearly colorless oil.
