実験手順

7.5 g (0.032 mole) of 3-tert.-butoxycarbonyl-thiazolidine-2-carboxylic acid and 5.2 g (0.032 mole) of N,N'-carbonyl-diimidazole are heated under reflux in 50 ml of tetrahydrofuran for 15 minutes. After addition of 6.1 g (0.03 mole) of 6-(4-aminophenyl)-5-methyl-4,5-dihydro-3(2H)-pyridazinone, the mixture is stirred at room temperature for 18 hours and concentrated and the residue is crystallised with ethyl acetate.
