Abstract
Opisan je postupak za dobijanje 4-(heteroaril-metil)-halogen-1(2H)ftalazinona, naročito 4-(4-piridilmetil)-1(2H)-ftalazinona, koji je naznačen reakcijom ftalidil-3-trifenilfosfonijum-soli sa 4-piridinaldehidom u prisustvu baznog sredstva i daljom reakcijom sa hidrazin hidratom kao i daljom obradom sa kiselinom, čime se ovim postupkom otklanjaju problemi osiguranja i zaštite čovekove sredine, a koje su postojale u ranije postojećim postupcima.[The invention relates to a method for producing 4-(heteroaryl-methyl)-halogen-1(2H)-phthalazinones, especially 4-(4-pyridylmethyl)-1(2H)-phthalazinone, which is characterized by the reaction of phthalidyl-3-triphenylphosphonium salt with 4- pyridine aldehyde in the presence of a basic auxiliary agent, by the subsequent reaction with hydrazine hydrate and by the subsequent acid treatment, whereby this method avoids the technical safety and environmental problems posed by prior art methods.
