Procedure

The title compounds were 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 methyl-2-amino-4,5-dimethoxybenzoate was used instead of 2′-amino-4′,5′-(methylenedioxy)acetophenone. The crude product was purified via HPLC to give N-(4-chloro-3-methyl-5-isoxazolyl)-2[(4,5-dimethoxy-2-methoxycarbonylphenyl)aminocarbonyl]thiophene-3-sulfonamide as a yellow powder (13% yield, m.p. 167-168° C.) and N-(4-chloro-3-methyl-5-isoxazolyl)2-{[4,5-dimethoxy-2,4,5-dimethoxy-2-methoxycarbonyl)phenyl]phenylaminocarbonyl}thiophene-3-sulfonamide as a dull yellow solid (1% yield, m.p. 228-230° C.).
