반응 단계
Starting with (3,6-difluoro-4-hydroxy-naphthalen-2-yl)-acetic acid methyl ester (25 mg, 0.099 mmol) and 2-bromo-5-ethanesulfonyl-pyridine (28 mg, 0.112 mmol), using a method analogous to the one described for the methyl ester of example 1-1, [4-(5-ethanesulfonyl-pyridin-2-yloxy)-3,6-difluoro-naphthalen-2-yl]-acetic acid methyl ester (20 mg, 48%) was obtained as a white solid, which was used in the next step without further purification.
