Procedure

The reaction was carried out in a manner similar to Example 84 except for using 2.00 g (10.2 mmol) of 5-chloro-2-indolecarboxylic acid, 1.82 g (11.3 mmol) of carbonyldiimidazole, 5.86 g (61.3 mmol) of guanidine hydrochloride, 6.20 g (61.3 mmol) of triethylamine, 50 ml of tetrahydrofuran and 50 ml of dimethylformamide. Thus 1.85 g (66.2%) of 5-chloro-2-indoloylguanidine hydrochloride was obtained.
