Reaction Conditions:

with potassium carbonate;(1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride in 1,4-dioxane at 90; for 4 h;

Steps:

1

Step 1. To a solution of 4-bromoaniline (1.50 g, 8.72 mmol) in 1 , 4-dioxane (50 mL) m-tolylboronic acid (1.42 g, 10.46 mmol), Pd(dppf)₂Cl₂ (100 mg) and K₂C0₃ (1.80 g, 13.08 mmol) were added. The mixture was heated to 90° C for 4 h. After cooling, the mixture was filtered. Then saturated aqueous NaHC0₃ (20 mL) was added to the filtrate and the resultant solution was extracted with EtOAc (100 mL x 3). The combined organic layers were dried over Na₂S0₄, concentrated and purified by SGC (DCM : PE = 1 : 3) to give 196 (300 mg, yield: 19 ). LC-MS (m/z): 184.1 [M+l]⁺.
