This relates to a process for preparing a 2-aminothiazole-carboxamide derivative that is represented by formula (1) in which R 1 represents C 1-5 alkyl, C 1-5 haloalkyl or C 3-6 cycloalkyl, straight or branched chain , and R2 represents C1-3 alkyl or C1-3 haloalkyl, characterized in that a compound represented by formula (2) in which R1 and R2 are defined as previously described and R3 represents phenyl, which may optionally be mono- to penta- If independently substituted by chlorine, methoxy, ethoxy, phenoxy or nitro, it is reacted with a compound represented by the formula (3) in which Y represents an outlet group, in a solvent, and in the presence of a base . In addition, a compound used as an intermediary in the above-mentioned process is sedivulted which is represented by the formula (2) in which R1, R2 and R3 are defined according to the above and a compound useful as an intermediate in the procedure mentioned above. It is represented by the formula (3) in which Y also seats according to the above. |
