Reaction Conditions

Reaction Steps

0.5 g of 5H,10H-imidazo[1,2-a]indeno[1,2-e]-pyrazin-4-one and 1.47 g of 3-methoxycarbonyl-benzaldehyde are refluxed for 48 hours in the presence of 0.7 g of ammonium acetate in 30 ml of acetic anhydride. After cooling to a temperature in the region of 20° C., the precipitate formed is filtered off, washed with water and dried under reduced pressure (1 mmHg; 0.13 kPa) at 50° C. 0.53 g of 10-(3-methoxycarbonyl-benzylidene)-5H-imidazo[1,2-a]indeno[1,2-e]pyrazin-4-one acetate is obtained in the form of a yellow powder, the melting point of which is greater than 260° C. (Analysis, C24H19 N3O5.0.19 H2O; % calculated C: 67.13; H: 4.46; N: 9.79; O: 18.63; % found C: 66.9; H: 4.4; N: 9.9; O: 18.6).
