The reaction was carried out in a manner similar to Example 196 e) except for using 0.60 g (1.27 mmol) of ethyl 7-[4-(tert-butoxycarbonylaminomethyl)-benzyloxy]-4-chloro-1-methyl-2-indolecarboxylate, 2.42 g (25.4 mmol) of guanidine hydrochloride, 1.37 g (25.4 mmol) of sodium methoxide and 50 ml of methanol. Thus, 0.25 9 (43.0%) of 7-[4-(aminomethyl)benzyloxy]-4-chloro-1-methyl-2-indoloylguanidine dihydrochloride was obtained.
