A 30-ml four-necked flask was equipped with a stirrer, a thermometer, a dropping funnel and a reflux condenser. 0.027 g (0.12 mmol) of palladium (II) acetate and 7 ml of N-methylpyrrolidinone were weighed in the flask, followed by stirring. Further, 0.072 g (0.12 mmol) of tricyclohexylphosphonium tetraphenylborate obtained in Example A-4 was weighed in air and added into the flask. The flask was purged with argon, followed by stirring at 25° C. for 30 minutes. 0.404 g (3 mmol) of n-heptyl chloride was added, followed by stirring at 25° C. for 30 minutes. 2 ml (4.4 mmol) of 2.2M tetrahydrofuran solution of phenylmagnesium chloride was added dropwise at 25° C. over a period of 10 minutes, followed by stirring at 25° C. for 19 hours. After the completion of the reaction, 6 ml of tetrahydrofuran and 10 ml of saturated aqueous ammonium chloride solution were added, followed by separation. The organic phase was purified by column chromatography to afford 0.435 g of 1-phenylheptane (yield: 82 mol % based on n-heptyl chloride). The identification of the product was made by mass spectroscopy.
