実験手順
0.9 g (3.26 mmol) 4b and 1.2 eqv. of aminoguanidine bicarbonate was mixed in 10 ml of ethanol and 2 ml of acetic acid and refluxed for 30 min. The solvent was evaporated and the oily residue was dissolved in acetonitrile and a few drops of diethyl ether was added. After three days in refrigerator a precipitate was formed that was filtered, washed with diethyl ether and dried. 340 mg (31%) of the final product 5b was obtained as white crystals (m.p. 166-168° C.).
