実験手順

N-[(5-Chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetyl]guanidine and N-[(6-chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetyl]guanidine are prepared as described in Example 9, starting with 20 cm3 of absolute ethanol, 0.35 g of sodium, 1.46 g of guanidinium chloride and 3.1 g of ethyl (5-chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetate and ethyl (6-chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetate in 15 cm3 of absolute ethanol. The reaction mixture is stirred at a temperature in the region of 20° C. for 18 hours and is then concentrated to dryness under reduced pressure (2 kPa) at a temperature in the region of 40° C. The residue is taken up in a mixture of 15 cm3 of water and 45 cm3 of diethyl ether and then stirred at a temperature in the region of 0° C. for 4 hours. The precipitate obtained is filtered off, washed with twice 20 cm3 of ice-cold water and then dried in a desiccator under reduced pressure (2 kPa) at a temperature in the region of 20° C. 1 g of N-[(5-chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetyl]guanidine and N-[(6-chloro-2-isobutyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetyl]guanidine is thus obtained in the form of a white powder. (Analysis: C15 H19 Cl N4 O2, % calculated C, 55.81; H, 5.93; Cl, 10.98; N, 17.36; O, 9.91%. found C, 55.67; H, 6.18; Cl, 11.32; N, 17.05). Mass spectrum: DCI: m/e 323 (M+H)+.
