9.5 g (0.048 mmol) of diisobutylaluminium chloride were added dropwise to a suspension, cooled to −40° C., of 12.1 g (0.048 mmol) of [8-(dimethylamino)naphth-1-yl]lithium etherate and 100 ml of diethyl ether in an inert nitrogen atmosphere. After slow warming to room temperature, the mixture was stirred for a further 24 hours in order to complete the reaction. Filtration through a D4 frit and removal of the solvent by distillation gave 10.6 g of [8-(dimethylamino)naphth-1-yl]diisobutylaluminium (71%) as a colourless, oily liquid by fractional distillation from the residue.
