Reaction Steps
In a similar manner, using phenol, p-cresol, o-chlorophenol, m-chlorophenol, o,p-dichlorophenol, m,p-dichlorophenol, m-trifluoromethylphenol, p-bromophenol, p-fluorophenol, m-fluorophenol, p-acetylphenol, p-cyanophenol, m-hydroxyphenol, and p-methoxyphenol in place of p-chlorophenol, the corresponding 1,2-diamino-4-phenoxy (or substituted phenoxy) benzenes and 2-carbomethoxyamino-5(6)-phenoxy (or substituted phenoxy) benzimidazole compounds are prepared. Using the 1,2-diamino compounds prepared above in this Example, and substituting 1,3-bis-ethoxycarbonyl-S-methyl isothiourea, 1,3-bis-propoxycarbonyl-S-methyl isothiourea, or 1,3-bis-butoxycarbonyl-S-methyl isothiourea for the 1,3-bis-methoxycarbonyl-S-methyl isothiourea, the corresponding 2-carbalkoxyamino-5(6)-phenoxy (or p-substituted phenoxy) benzimidazole compounds are prepared, where R is ethyl, propyl or butyl.
