Reaction Steps
To a mixture of (R)-2-methylpiperazine (3.0 g, 30 mmol), 4-trifluoromethoxy bromo benzene (6.6 g, 27.5 mmol) and sodium tert-butoxide (3.56 g, 37.5 mmol) in dry toluene (50 mL) under nitrogen atmosphere, were added Pd(OAc)2 (0.28 g, 12.5 mmol) followed by BINAP (0.62 g, 1 mmol) and refluxed for 16 h. Then the reaction mixture was concentrated and the crude compound was purified by column chromatography on silica gel using chloroform and methanol as eluent to give the title compound as a dark brown liquid (3 g, 38%).
