Versuchsvorschrift
A ethanol (8 ml) solution of 1-(3-fluorophenyl)-2-chloromethylbenzimidazole (1.0 g, 4 mmol) prepared in the preceding step (b) and 4-aminopyridine (1.3 g, 7.4 mmol) was refluxed for 1.5 hours. The reaction mixture was concentrated in vacuo and crystallized from acetone and recrystallized from ethanol-acetone, then the objective compound (0.3 g, 0.82 mmol) was obtained.
