Patent ID: 7858805

Claim:
A process for preparing a compound of formula (I) or salts thereof: in which Q 1 represents O, Q 2 represents O, R 1 represents —CH 3 , R 2 represents —CH 3 , R 3 represents —OCH 3 , and R 4 represents —CH 3 , the process comprising: (b) reacting a substituted thien-3-yl-sulphonyl iso(thio)cyanates of the general formula (IV) in which Q 1 , R 1 and R 2 are each as defined above, with triazolin(ethi)ones of the formula (V) in which Q 2 , R 3 and R 4 are each as defined above, if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, or (c) reacting a substituted thiophene-3-sulphonyl chlorides of the formula (VI) in which R 1 and R 2 are each as defined above, with triazolin(ethi)ones of the formula (V) in which Q 2 , R 3 and R 4 are each as defined above, and metal (thio)cyanates of the formula (VII) M-Q 1 -CN (VII) in which Q 1 is as defined above, if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, or (d) reacting substituted thiophene-3-sulphonyl chlorides of the formula (VI) in which R 1 and R 2 are each as defined above, with triazolin(ethi)one-(thio)carboxamides of the formula (VIII) in which Q 1 , Q 2 , R 3 and R 4 are each as defined above, if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, or (e) reacting substituted thien-3-yl-sulphonylamino(thio)carbonyl compounds of the formula (IX) in which Q 1 , R 1 and R 2 are each as defined above, and Z represents halogen, alkoxy, aryloxy or arylalkoxy, with triazolin(ethi)ones of the formula (V) in which Q 2 , R 3 and R 4 are each as defined in above, if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent.
