    CPC classification number: C07D209/48

    Abstract: The invention concerns the preparation of 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) (R1 = H, halogen; R2, R3 = halogen; R4 = C-organic rest; R5 = H, CH¿3?) by the reduction of 3-nitrocinnamic acid esters of formula (II) with hydrogen in the presence of a catalyst and the condensation of the 3-aminocinnamic acid esters obtained of formula (III) with a 3,4,5,6-tetrahydrophthalic acid anhydride of formula (IV). 3-(3,4,5,6-tetrahydrophthalimido)cinnamic acid esters of formula (I) are useful active agents in the plant-protection field.

    Abstract: The invention relates to processes for preparing 2-aminomethyl-4-cyanothiazole and its salts of the formulae Ia and Ibin whichn=1 or 2 andfor n=1, X is chloride, bromide, triflate and hydrogen sulfate andfor n=2, X is sulfate, which comprises the process step where the aminonitrile of the formula IIis stirred with a cysteine ester of the formula III,in which R is branched or linear C1-10-alkyl orwhere n=0, 1 or 2 and R is branched or linear C1-C10C10-alkyl or C1-C4-alkoxy or C1-C4-dialkylamino in an inert solvent in the presence of a base at from 0° C. to 80° C. until the reaction has essentially proceeded to completion, and to the compounds of the formulae Ia and Ib.
