A solution of (2R)-2-(aminomethyl)-1,1,1-trifluoro-4-[5-fluoro-2-(methyloxy)phenyl]-4-methyl-2-pentanol (Intermediate 21, 20 mg, 0.065 mmol), 4-bromo-1-(2,4-difluorophenyl)-6-methyl-1H-indazole (Intermediate 13, 18.3 mg, 0.057 mmol), tris(dibenzylideneacetone)dipalladium(0) (2.6 mg, 0.0028 mmol), racemic-BINAP (3.6 mg, 0.0056 mmol) and sodium tert-butoxide (7.7 mg, 0.081 mmol) in toluene (0.4 mL) was heated in a microwave at 120° C. for 15 min. The mixture was then cooled, partitioned between ethyl acetate (20 mL) and aqueous ammonium chloride (20 mL). The organic layer was separated, washed successively with aqueous sodium bicarbonate, water and brine, passed through a hydrophobic frit and evaporated. The residue was purified by mass-directed autopreparation to give the title compound (6.5 mg).
