Reaction Steps

As illustrated in Formula 7, the product 4a in Formula 6 (1.2 g, 2.46 mmol), 7-tert-butylpyren-1-ylboronic acid (2.23 g, 7.38 mmol), potassium carbonate solution (2.0 M, 10 mL), and dried toluene (30 mL) were charged in a two-necked bottle. The bottle was deoxygenated and purged with nitrogen, and the mixture in the bottle was stirred at 60° C. until it was totally dissolved. The nitrogen pressure of the bottle was increased, and Pd(PPh3)4 (289 mg, 0.25 mmol) was rapidly added into the bottle. The reaction was heated to 110° C., and stirred for 48 hours. The resulting was cooled to room temperature to precipitate a solid, and the solid was collected by filtering. The solid was sublimated at a temperature of 330° C. to obtain a white solid of 1.56 g (yield=75%).
