Reaktionsschritte

A mixture of 1-acetyl-1-(3-nitrobenzyliden)acetone (10 g), benzamidine hydrochloride (8.06 g) and triethylamine (8.4 ml) in n-butanol (100 ml) was refluxed for 2 hours. The reaction mixture was added ethyl acetate (100 ml), washed with water (100 ml) and 5% hydrochloric acid (100 ml) successively. The solvent was evaporated and the residue was stirred with ethyl acetate (100 ml) for 1 hour. The crystals were collected by filtration, added a mixture of chloroform (100 ml) and water (100 ml) and adjusted to pH 8.5 by saturated potassium carbonate. The organic layer was evaporated in vacuo to give 5-acetyl-4-methyl-6-(3-nitrophenyl)-2-phenyl-1,6-dihydropyrimidine (4.46 g).
