反応手順

1.02 g (7.2 mmol) of 2-chloro-6-methylaniline, 1.23 g (7.2 mmol) 4-bromotoluene, 1.15 g (12 mmol) sodium tert-butoxide, 160 mg (0.7 mmol) tri-tert-butyhphosphine and 130 mg (0.23 mmol) bis-dibenzylideneacetone-palladium(0) are reacted in 50 ml toluene under nitrogen at 90° C. for 20 minutes and at 60° C. over night. Aqueous workup (3N HCl, with hyflo, washing the organic phase with water) and flash-chromatography on silica using heptan/toluene (4:1) as the eluent affords 1.49 g of N-(2′-chloro-6′-methylphenyl)-4-methylaniline.
