Procedure

152.2 g (1.0 mole) of DBU and 47.6 g (0.5 moles) of anhydrous MgCl2 were refluxed in 300 g of methanol with heating for 8 hours, and then cooled. The deposited crystals were recovered therefrom by filtration, washed with acetone and dried, whereby 145.2 g of DBU/MgCl2 complex compound was obtained (yield: 72.7%).
