Reaktionsschritte

4-Methylcyclohexanone (224 g, 2 moles) was added dropwise rapidly to a cooled, stirred suspension of 170 g (4 moles) of sodium amide in 2 l of tetrahydrofuran under nitrogen. After the addition was complete, the ice bath was removed and the mixture was heated at reflux until the evolution of ammonia ceased (~3 hours). While still at reflux, 142.5 g (1 mole) of o-chloroanisole was added rapidly dropwise and the mixture was heated for an additional hour, until evolution of ammonia ceased.
