Procedure
1-(7-Ethoxycarbonylheptyl)-2-heptyl-4,5-diphenyl-imidazole (1 g) was reacted with sodium hydroxide in a method similar to Example 10 to give, after colnmn chromatography on silica gel (dichloromethane/methanol) and recrystallisation from hexane, 1-(7-carboxyheptyl)-2-heptyl-4,5-diphenylimidazole (0.26 g, 28%) as a white solid, m.p. 75°-6°. Found: C, 78.04; H, 8.85; N, 6.10%; C30H40N2O2 requires: C, 78.22; H, 8.75; N, 6.08%;
