Reaction Steps

To a hot (60° C.) solution of 2-aminobenzimidazole (0.22 g; 1.65 mmol) in DMF (25 ml) was added sodium hydride (70 mg; 60% dispersion in mineral oil), and the mixture was stirred for 30 minutes prior to addition of cis-1,5-bis(p-toluenesulfonyloxy)cyclooctane. The resulting mixture was stirred at 100° C. for four days, cooled and filtered. The filtrate was diluted with water and the precipitate was filtered off, washed with water and dried to yield the desired product (9 mg).
