The compounds of the formula (I) <IMAGE> in which R1 represents C1-C4-alkyl, C1-C4-alkoxy or halogen, R2 represents hydrogen, C1-C3-alkyl, C1-C4-alkoxy or halogen, R7 represents hydrogen, C1-C3-alkyl, C1-C4-alkoxy or halogen, R8 represents hydrogen or methyl, the total of C atoms of the substitutents R1, R2, R7 and R8 in the phenyl ring not exceeding 8, X represents <IMAGE> R3 represents <IMAGE>, where R', R'' and R''' independently of one another represent hydrogen, methyl or ethyl and R4 represents C1-C6-alkyl, C3-C6-alkenyl or C3-C6-alkynyl, each of which is optionally substituted by a halogen atom, or represents benzyl which is optionally substituted by halogen or C1-C4-alkyl, with the exception of what is protected in Patent Claim I of the Main Patent No. 594,619, are prepared by reacting a compound of the formula (II) <IMAGE> with a compound of the formula III <IMAGE> where hal denotes halogen, at a temperature of 0 to 180 DEG C. The active substances of the formula (I) have a microbicidal spectrum which is very favourable for practical requirements. They have a particularly good activity against phytopathogenic fungi.
