Reaction Steps

A mixture of Methyl 3,4-diaminobenzoate (1.84 g) and 4-hexyloxy benzaldehyde (2.30 g) in nitrobenzene (40 ml) was stirred for 48 hours at 145° C. After cooling, the mixture was evaporated under reduced pressure. Purification of the residue by column chromatography on silica gel eluted with (n-hexane:ethyl acetate=2:1) gave 5-Methoxycarbonyl-2-(4-hexyloxyphenyl)benzimidazole (1.19 g).
