This invention relates to intermediate compounds which are useful for making substituted 1-phenyl-3-pyrazolecarboxamides. The compounds of the invention have the formula: ##STR1## in which: R'.sub.2 and R'.sub.3 each independently represent a hydrogen, a (C.sub.1 -C.sub.6)alkyl, a (C.sub.3 -C.sub.8)cycloalkyl, a (C.sub.3 -C.sub.8)cycloalkylmethyl; or R'.sub.2 and R'.sub.3 together constitute a trimethylene, tetramethylene or pentamethylene group; R.sub.y is at position 4 or at position 5 and represents a group chosen from: cyano, carboxyl, (C.sub.1 -C.sub.4)alkoxycarbonyl, benzyloxycarbonyl, sulpho, (C.sub.1 -C.sub.4)alkylsulphonylamino, (C.sub.1 -C.sub.4)alkylphenylsulphonylamino, carbamoyl, (C.sub.1 -C.sub.4)alkylcarboxamido; on condition that R'.sub.2 and R'.sub.3 do not simultaneously represent hydrogen and on condition that R'.sub.2 is other than methyl when R.sub.y is a sulpho group. The salts of the above compounds are also part of the invention.
本发明涉及中间化合物,其用于制备取代的1-苯基-3-吡唑羧酰胺。本发明中的化合物具有以下结构式:##STR1## 其中:R'.sub.2和R'.sub.3各自独立地表示氢、(C.sub.1-C.sub.6)烷基、(C.sub.3-C.sub.8)环烷基、(C.sub.3-C.sub.8)环烷基甲基;或R'.sub.2和R'.sub.3共同构成三亚甲基、四亚甲基或五亚甲基基团;R.sub.y位于4位或5位,并表示从以下组中选择的一组:氰基、羧基、(C.sub.1-C.sub.4)烷氧羰基、苄氧羰基、磺酰基、(C.sub.1-C.sub.4)烷基磺酰氨基、(C.sub.1-C.sub.4)烷基苯基磺酰氨基、氨基甲酰基、(C.sub.1-C.sub.4)烷基羧酰胺;条件是R'.sub.2和R'.sub.3不能同时表示氢,并且当R.sub.y为磺酰基时,R'.sub.2不得为甲基。上述化合物的盐也是本发明的一部分。
