Procedure

By substituting 5-amino-1,3-benzodioxole for 4-(trifluoromethyl)aniline in a, and then substituting the appropriate substituted propiolic ester for ethyl propiolate and/or the appropriate stubstituted nitromethane for nitroethane in a, the identical process gives 4-(1,3-benzodioxol-5-aminocarbonyl)-3-methylisoxazole, 4-(1,3-benzodioxol-5-aminocarbonyl)-3-cyclopropylisoxazole, 4-(1,3-benzodioxol-5-aminocarbonyl])-3,5-dimethylisoxazole, 4-(1,3-benzodioxol-5-aminocarbonyl)-3-cyclopropyl-5-methylisoxazole, and 4-(1,3-benzodioxol-5-aminocarbonyl)-5-(2-chlorophenyl)-3-methylisoxazole, and 4-(1,3-benzodioxol-5-aminocarbonyl)-5-(2-chlorophenyl)-3-cyclopropylisoxazole.
