Procedure

To a solution of ethyl 4-(N-benzyl-N-methylaminomethyl)-2-[N-(2,6-difluorobenzyl)-N-ethoxycarbonylamino]-5-[4-(3-methoxyureido)phenyl]thiophene-3-carboxylate (3.64 g, 5.47 mmol) in ethanol (100 ml) were added 1N hydrochloric acid (8 ml) and 10% palladium-carbon (50% wet, 1.82 g). The mixture was stirred vigorously under hydrogen atmosphere for 6 hours. The catalyst was removed, and the filtrate was neutralized with 1N sodium hydroxide solution. The solvent was distilled off, and the residue was distributed between ethyl acetate and water. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was subjected to an NH-silica gel (Fuji Silysia Chemical) chromatography to give the title compound (2.43 g, 77%) as yellow powders.
