Participants

Reaction Steps

Under the nitrogen atmosphere, (10-(naphthalen-1-yl)anthracen-9-yl)boronic acid (25.1 g), 7-methoxynaphthalen-2-yl trifluoromethane sulfonate (24.3 g), Pd(PPh3)4 (0.9 g), potassium phosphate (30.6 g), and a mixture solvent (260 ml) of pseudo cumene, IPA, and water (pseudo cumene/IPA/water=8/4/1 (volume ratio)) were added to a flask and refluxed for 4.5 hours. Once the heating is completed, water was added. After cooling to room temperature, a solid was collected by suction filtration. The obtained solid was washed with water and subsequently with methanol, dissolved in toluene, and purified with a silica gel short column. Crystals obtained by slow distillation of the solvent under reduced pressure were collected by suction filtration to give 9-(7-methoxynaphthalen-2-yl)-10-(naphthalen-1-yl)anthracene (17.5 g) as a third intermediate compound. The scheme is shown in the following “Reaction 4”.
