実験手順
In the glass liner of a stainless steel bomb cooled to -78° is condensed 10 ml. of methylamine. To this is added 0.5 ml. of 2 M n-butyllithium (in hexane), followed by 5.0 g. of 2-benzoyl-3-methoxycrotononitrile. The bomb is sealed and heated on a steam bath overnight. The bomb is then cooled, opened and the contents evaporated. The residue is dissolved in chloroform, passed through a Magnesol® pad and the filtrate is evaporated. The residue is recrystallized from chloroform-hexane yielding the title compound.
