Reaction Steps

A 568 mg portion of 1-[3-(2-azido-1-hydroxyethyl)phenyl]-3-(3,5-difluorophenyl)-2-(1,3-dihydro-2H-benzimidazol-2-ylidene)propane-1,3-dione and 120 mg of 10% palladium-carbon were added to 50 ml of ethyl acetate and stirred at room temperature for 8.5 hours under ordinary pressure and in an atmosphere of hydrogen. This was filtered through celite, concentrated, mixed with diethyl ether and then extracted with water. By concentrating the water layer, 250 mg (47%) of 1-[3-(2-amino-1-hydroxyethyl)phenyl]-3-(3,5-difluorophenyl)-2-(1,3-dihydro-2H-benzimidazol-2-ylidene)propane-1,3-dione (Example 14-1) was obtained as a yellow solid.
