실험 절차

A 100-ml four-necked flask was equipped with a stirrer, a thermometer and a reflux condenser. 7.536 g (48 mmol) of bromobenzene, 6.769 g (40 mmol) of diphenylamine, 4.613 g (48 mmol) of sodium-tert-butoxide, 0.009 g (0.04 mmol) of palladium (II) acetate and 5 ml of xylene were weighed in the flask, followed by stirring. Further, 0.071 g (0.12 mmol) of di-tert-butyl-1-naphthylphosphonium tetraphenylborate obtained in Example B-11 was weighed in air and added into the flask. The flask was purged with argon, followed by stirring at 125° C. for 4 hours. After the completion of the reaction, 45 ml of xylene and 50 ml of saturated sodium chloride solution were added, followed by separation. The organic phase was purified by column chromatography to afford 8.341 g of triphenylamine (yield: 85 mol % based on diphenylamine). The melting point was 125-126° C.
