実験手順

A solution of 0.24 g (0.001 mol) of 4-amidino-2,3-dihydro-1H-inden-1-one hydrochloride and 0.136 g (0.001 mol) of 1,2-diamino-4,5-dihydro-imidazole hydrochloride [m.p. 245°-246° C., prepared from the corresponding p-toluenesulfonate salt, see EP 0 327 919, Example 12, by ion exchange on ®Amberlite IRA-400 (anion exchanger based on a styrene/divinylbenzene polymer with quaternary ammonium groups in the Cl- form; Fluka, Buchs, Switzerland)] in 3 ml of water is left to stand at room temperature for 18 hours. The product that has crystallized out is filtered off with suction and recrystallized from water, yielding the title compound (monohydrate), m.p. 280° C. (decomp.), 1 H-NMR (DMSO/D2O): δ=8.17 (d, 1H); 7.66 (d, 1H); 7.54 (t, 1H); 4.18 (t, 2H); 3.70 (t, 2H); 3.25 (m, 2H); 3.13 (m, 2H).
