반응 단계
To a solution of 6.5 g of 1,3-dihydro-4-methyl-2H-imidazol-2-one and 14.6 g of aluminum chloride in 65 ml of nitrobenzene is added 17.6 g of 3,4-dimethoxybenzoyl chloride in portions. The mixture is stirred for 3 hours at 60° C., cooled and poured over ice water. The gummy solids are filtered and recrystallized twice from ethyl alcohol-water to afford the title compound. M.P. 257°-259° C.
