反応手順
N-(4-chloro-3-methyl-5-isoxazolyl)-2-[(2-cyano-4,5-dimethoxyphenyl)aminocarbonyl]thiophene-3-sulfonamide was prepared by the method set forth for N-(4-chloro-3-methyl-5-isoxazolyl)2-{[2-acetyl-4,5-(methylenedioxy)phenyl]aminocarbonyl}thiophene-3-sulfonamide (EXAMPLE 148) except that 2-amino-4,5-dimethoxybenzonitrile was used instead of 2'-amino-4',5'-(methylenedioxy)acetophenone. N-(4-chloro-3-methyl-5-isoxazolyl)-2-[{2-cyano-4,5-dimethoxyphenyl)aminocarbonyl]thiophene-3-sulfonamide was obtained via HPLC purification as a light brown powder (36% yield, m.p. 53°-56° C.).
