We have recently reported an alternative liquid precursor for the CVD of aluminum thin films.3 The main advantage of (AT,AT-dimethylethanamine)-trihydridoaluminum, frequently referred to by its trivial name dimethylethyl-amine alane (DMEAA), over (trimethylamine) trihydridoaluminum is that DMEAA is a liquid at room temperature, which provides stationary pressure conditions for better control of precursor transport. Analogous to the previously reported synthesis of (trimethylamine)trihydridoaluminum,4 the reaction of lithium tetrahydroaluminate(l —) with AT,AT-dimethyl-ethanaminium chloride in diethyl ether generates the stable liquid precursor DMEAA with high yield. 

The last of the butyl isomers, the tert-butyl compound, was made from a much more obvious starting material. This is the commercially available tert-butyl hydroquinone. It was methylated in sodium hydroxide with methyl iodide, and then carried through the above sequence (benzaldehyde. mp 124 °C from cyclohexane, nitrostyrene, yellow crystals from methanol, mp 95-96.5 °C, and lithium aluminum hydride reduction) to give 2,5-dimethoxy-4-(l,l-dimethylethyl)amphetamine hydrochloride (DOTB, mp 168 °C). Rats trained in a process called the Sidman Avoidance Schedule gave behavior that suggested that DOTB had no activity at all, and in human trials, doses of up to 25 milligrams were totally without effect.
