Reaction Steps

A solution of 3-bromo-5-(trifluoromethyl)aniline (3.24 g, 13.5 mmol) in N,N-dimethylformamide (50 mL) was degassed by bubbling argon through the solution for 30 minutes. To the reaction was added zinc cyanide (0.872 g, 7.42 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.624 g, 0.54 mmol). The reaction was heated to 80° C. and stirred for 20 hours. The solvent was removed from the reaction under vacuum and the residue purified by silica chromatography (Biotage SP4, eluting 15% EtOAc in iso-hexane (4 column volumes) then a gradient from 15-30% (over 6 column volumes)) to yield the title compound as a colourless oil (2.20 g).
