After the reaction was over, silica gel was added to the filtrate to produce sand. The crude product was obtained by silica gel column chromatography and then washed with methanol or pentane-DCM to obtain a green solid product 8e with a yield of 74%.

RuCl2 (PPh3) 3 (800 mg, 0.83mmol) and (1R, 2R) -1, 2-diphenylethylenediamine (195 mg, 0.92 mmol) are weighed and charged into a 20-mL Schlenk flask. The flask was reduced pressure to degas therein and then nitrogen gas was introduced into the flask. Dichloromethane (8 mL) was added thereto through a syringe, and the mixture was stirred under nitrogen atmosphere at room temperature for 3 hours. The reaction solution was then Celite-filtered, and the Celite layer was washed with dichloromethane (2mL). The filtrate obtained was concentrated under reduced pressure to a volume of about 2 mL; hexane (16 mL) was added thereto; and the mixture was stirred at room temperature for 1 hour. The precipitate was collected by filtration under nitrogen atmosphere, and the powder obtained was dried under reduced pressure (1 mmHg), to give 531 mg of a desired product (yield: 70%).
