| titleOfInvention | Process for the preparation of alkoxytriazolinones |
| abstract | Alkoxytriazolinones of the formula (I), ##STR1## are obtained in good yields and in high purity by reacting iminocarbonic diesters (II) with carbazinic esters (III) ##STR2## at -20° C. to +120° C. (1st step) and subjecting the semicarbazide derivatives (IV) formed in this process with elimination of R 2 --OH ##STR3## to a cyclizing condensation reaction in the presence of a base at 20° C. to 150° C. with elimination of R 3 --OH, if appropriate (2nd step) and, finally, by reacting the resulting 5-alkoxytriazolinones of the formula (V) =formula (I) where R 1 =H! with an alkylating agent of the formula R 1 --X (VI) at 0° C. to 150° C., if appropriate in the presence of a base. |
