Diethyl Ether → HCID 15529887, compound

Participants

Reaction Steps

Into a 1 liter egg plant-shaped flask, 4.9 g (0.2 moles) of magnesium was weighed and placed. Under the stream of nitrogen gas, 80 ml of diethyl ether was added and stirred. Then, a solution prepared by dissolving 27.4 g (0.2 moles) of n-butyl bromide into 20 ml of diethyl ether was added dropwise. After the addition was completed, the resultant mixture was heated under the refluxing condition for 30 minutes. The temperature was adjusted at the room temperature, and diethyl ether was completely removed using a vacuum pump. Then, a solution prepared by dissolving 27.1 g (0.1 mole) of 1-bromo-3-(n-butyl)adamantane obtained in accordance with the process described above in 1-2) into 300 ml of dichloromethane was added dropwise. After the addition was completed, the resultant mixture was heated under the refluxing condition for 5 hours. The reaction fluid was poured into 200 ml of ion-exchanged water and treated by extraction with dichloromethane using a separation funnel. The solvent was removed using an evaporator. The residue was dissolved into 20 ml of hexane and purified in accordance with the silica gel column chromatography (the solvent of development: hexane). The solvent was removed using an evaporator, and 8.20 g of 1,3-di(n-butyl)adamantane of the object compound was obtained (the yield: 33%).
