Participants

Reaction Steps

The process is performed as in Example 3 but starting with 4.7 g of 10-(4-acetylaminobenzylidene)-5H,10H-imidazo[1,2-a]indeno[1,2-e]pyrazin-4-one, 250 ml of dimethylformamide, 50 ml of methanol and 0.6 g of 10% palladium-on-charcoal for 26 hours. 1.2 g of 10-(4-acetylaminobenzyl)-5H,10H-imidazo[1,2-a]indeno-[1,2-e]pyrazin-4-one are obtained in the form of a cream-white solid melting above 260° C. (Analysis, % calculated C: 71.34, H: 4.90, N: 15.13, O: 8.64, % found C: 71.3, H: 4.7, N: 15.3, O: 8.3).
