Procedure
5′-(5-Cyano-1-methyl-1H-pyrrol-2-yl)spiro[cyclohexane-1,3′-[3H]indol]-2′-ylidenecyanamide (0.96 g) in ethanol (20 mL) was reacted with the bases set forth in Table 2 to form, upon cooling, filtering and drying, 5′-(5-cyano-1-methyl-1H-pyrrol-2-yl)spiro[cyclohexane-1,3′-[3H]indol]-2′-ylidenecyanamide salt as a solid. The 1H-NMR spectra (DMSO-d6) of the purified compound (X═H) and isolated salts (X═Na, K, choline, and Et2NH.H) were obtained and the data compiled in Table 2.
