Versuchsvorschrift

2-Bromo-5-chloro-3-methyl-phenylamine (595 mg, 2.7 mmol, Example 135: step c), Pd(OAc)2 (30.3 mg, 0.14 mmol), 2-(dicyclohexylphosphino)biphenyl (189.2 mg, 0.54 mmol) and Et3N (1.5 mL, 10.8 mmol) were dissolved into dioxane (10 mL). To this was added 4,4,5,5-Tetramethyl-[1,3,2]dioxaborolane (1.2 mL, 8.1 mmol) slowly. The reaction was heated to 80° C. overnight. The solvents were removed in vacuo and the resulting residue was dissolved into EtOAc and washed with brine. The combined organic layers were dried (MgSO4) and removal of the solvents in vacuo resulted in a mixture of the title compound and 3-Methyl-2,5-bis-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylamine were obtained and used with out further purification.
