Reaction Steps

Following the procedure of this example, N-(3-bromopropyl)phthalimide with 4-methylimidazole and 2-ethylimidazole were used to produce respectively 2-[3-(4-methyl-1H-imidazol-1-yl)propyl]isoindole-1,3-(2H)-dione and 2-[3-(2-ethyl-1H-imidazol-1-yl)-propyl]isoindole-1,3(2H)-dione which again following the procedure of this example were converted respectively to (4-methyl-1H-imidazol-1-yl)-1-propanamine dihydrochloride and (2-ethyl-1H-imidazol-1-yl)-1-propanamine dihydrochloride which were then converted by the procedure of Example 1, using the appropriate acid chloride, to the products of Examples 21-27, listed in Table V.
