実験手順

N-(4-chloro-3-methyl-5-isoxazolyl)-2-ethylbenzo[b]furan-3-sulfonamide compound was prepared by the method of Example 41 with 4-chloro-3-methyl-5-amino-isoxazole (1.0 mmols, 0.13 g), NaH (2.5 mmols, 60 mg), 2-ethylbenzo[b]furan-3-sulfonyl chloride (1.2 mmols, 0.28 g) and THF (7 ml). Flash chromatography (20% ethyl acetate/hexanes) followed by recrystallization from chloroform and hexane provided 97 mg (28%) of a white solid, m.p. 132°-133.5° C.
