Procedure

To a solution of N-cyclopropyl-1-{4-[(ethylamino)carbonyl]phenyl}-5-[(E)-2-(1,3-thiazol-2-yl)vinyl]-1H-1,2,3-triazole-4-carboxamide (130 mg) obtained in Example 321 in DMF (10 ml) was added 10% Pd/C (50% wet, 15 mg), and the mixture was stirred for 3 days under a hydrogen atmosphere. After the reaction mixture was filtered through celite, the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column (ethyl acetate to ethyl acetate/methanol=4/1) to give the title compound as a white powder (100 mg).
