Procedure

2-Bromoanisole (5.61 g, 30 mmol) and 4-dibenzothiopheneboronic acid (6.84 g, 30 mmol), Pd2(PPh3)4 (1.00 g, 0.8 mmol) were dissolved in 100 ml of toluene. Saturated solution of sodium carbonate (12.5 g in water) was added, and reaction mixture was heated to reflux under N2 atmosphere overnight. Then reaction mixture was cooled down to room temperature, separated organic phase and evaporated toluene. The solid residue was subjected to column chromatography on silica (eluent—hexane/ethyl acetate 4/1) providing 4-(2-methoxyphenyl)dibenzo[b,d]thiophene as 6.6 g of colorless solidified oil.
