実験手順

In a manner analogous to example 1 d, the process is carried out by a reaction of 4.1 g (16 mmol) of (4-bromo-2-tert-butylphenyl)dimethylamine with 9.6 ml (24 mmol) of a 2.5M solution of n-butyllithium and 1.9 ml (24 mmol) of DMF. 2 g of 3-tert-butyl-4-dimethylaminobenzaldehyde are obtained in the form of a yellow oil (yield=100%).
