Reaction Conditions

Reaction Steps

A solution of n-hexanol (30.6 g) in tetrahydrofuran (400 ml) was slowly added to solution of N,N-carbonyldiimidazole (55.08 g) in tetrahydrofuran (100 ml) and stirred for 2½ hour at 25-35° C. to provide hexyl 1H-imidazole-1-carboxylate compound of formula-4. 1-methyl-2-[N-[4-amidinophenyl]aminomethyl]benzimidazol-5-yl-carboxylicacid-N-(2-pyridyl)-N-(2-ethoxycarbonylethyl)amide compound of formula-5 (100 g), tetrahydrofuran (700 ml), water (800 ml) and potassium carbonate (138 g) were added to the reaction mixture and stirred for 20 hours at 25-30° C. After completion of the reaction, filtered the solid, washed with tetrahydrofuran and then dried to get title compound.
