실험 절차

To a suspension of 3,4-dihydro-6-(3,4-dimethoxyphenyl)-3-methyl-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone (0.63 g) in N,N-dimethylformamide (15 ml) were added potassium hydroxide (0.16 g) and ethyl iodide (0.66 ml) and the mixture was stirred at ambient temperature for 4 hours. The mixture was poured into water (100 ml), and was extracted with chloroform. The extract was washed with water, dried over magnesium sulfate, and evaporated under reduced pressure. The residue was chromatographed on silica gel eluting with chloroform to give 3,4-dihydro-6-(3,4-dimethoxyphenyl)-1-ethyl-3-methyl-4-(2,4,6-trimethylphenylimino)-2(1H)-pyrimidinone (0.39 g).
