Versuchsvorschrift
1-Methylpiperazine (1.811 g) was added to ethyl 1-octadecyl-1H-benzimidazole-2-carboxylate (1.601 g) and the mixture was stirred for 48 hours at 75° C. The reaction mixture was purified by silica gel column chromatography (silica gel 60 g, chloroform:methanol=1:0-50:1), thereby yielding the entitled compound (1.070 g) as pale yellow solid.
