Rotary Evaporator Diethyl Ether

Rotary Evaporator Diethyl Ether

combined in 150 mL diethyl ether, stirred for 1.5 minutes, and then filtered into a round bottom flask. The volume of the solution was reduced by using a rotary evaporator (without a water bath) until dark red needles formed and the product was collected by filtration, washed with cold pentane, and stored in the freezer.
