実験手順

Acetyl chloride (8 ml) was added dropwise to a cooled (0° C.) solution of 1,2-dihydro-6-methoxy-2,2,4-trimethylquinoline (1.7 g) and a catalytic amount of N,N-dimethylaminopyridine in pyridine (60 ml). After stirring for 18 h, the reaction mixture was concentrated in vacuo. The residue was dissolved in dichloromethane and washed with 1 M HCl, water, 5% aq. NaHCO3, water and brine. The organic layer was dried (MgSO4) and concentrated in vacuo. The residue was chromatographed on silicagel in dichloromethane as eluent.
