실험 절차

The product obtained in the same manner as in Example 133e) from ethyl 1-{4-[(ethylamino)carbonyl]-2-hydroxyphenyl}-1H-1,2,3-triazole-4-carboxylate (2.37 g) obtained in Example 133c) was dissolved in DMF (18 ml), cyclopropylamine (0.51 ml), triethylamine (1.01 ml), HOBt (1.12 g) and WSC (1.40 g) were successively added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was acidified with 1N hydrochloric acid. The precipitated crystals were collected by filtration and washed with water to give the title compound as a pale-brown powder (1.41 g, yield in 2 steps 59%).
