Definitions
- the present invention relates to a process for the preparation of 2- (phenylimino) -l, 3-thiazolidin-4-ones of the general formula (I).
- 2- (Phenylimino) -l, 3-thiazolidin-4-ones and corresponding derivatives are of great importance in the pharmaceutical and agrochemical industry as intermediates for the production of, for example, chiral sulfoxides.
- Such sulfoxides are used, for example, in crop protection as acaricidal agents (see, for example, WO2013 / 092350 or WO2015 / 150348).
- a process that has become known for the preparation of 2- (phenylimino) -l, 3-thiazolidin-4-ones of the general formula (I) is accordingly characterized in that an aniline of the general formula (IV) is mixed with an isothiocyanate in a first step of the general formula (V) or an aryl isothiocyanate of the general formula (VI) is reacted with an amine of the general formula (VII) and then the thiourea of the general formula (II) thus formed is isolated, for example by filtration.
- the thiourea of the general formula (II) is then combined with an acetic acid derivative of the general formula (III) in the presence of a base to give 2- (phenylimino) -l, 3-thiazolidin-4-one of the general formula ( I) implemented.
- 2- (phenylimino) -l, 3-thiazolidin-4-ones of the general formula (I) can be prepared by adding an aniline of the general formula (IV) in the presence of an acetic acid derivative of the general formula (III) and a base is reacted with an isothiocyanate of the general formula (V), the thiourea of the general formula (II) formed as an intermediate reacting directly and preferably in situ to give the 2- (phenylimino) -l, 3-thiazolidin-4-one.
- the present invention accordingly provides a process for the preparation of 2- (phenylimino) - l, 3-thiazolidin-4-ones of the general formula (I) in which
- Y 1 and Y 2 independently represent fluorine, chlorine or hydrogen
- R 1 and R 2 independently represent hydrogen, (Ci-Ci 2 ) alkyl, (Ci-Ci 2 ) haloalkyl, cyano, halogen or nitro, and
- R 3 represents optionally substituted (Ce-Cio) aryl, (Ci-Ci 2 ) alkyl or (Ci-Ci 2 ) haloalkyl, the substituents being selected from halogen, (Ci-C 6 ) alkyl, (C 3 -Cio ) Cycloalkyl, cyano, nitro, hydroxy, (Ci-C 6 ) alkoxy, (Ci-C 6 ) haloalkyl and (Ci-C 6 ) haloalkoxy, in particular from fluorine, chlorine, (Ci-C 3 ) alkyl, (C 3 -C 6 ) Cycloalkyl, cyclopropyl, cyano, (Ci-C 3 ) alkoxy, (Ci-C 3 ) haloalkyl and (Ci-C 3 ) haloalkoxy, which is characterized in that an aniline of the formula (IV)
- X stands for bromine, chlorine, OSCFMe, OSCFPh, 0S0 2 (4-Me-Ph) or OSO2CF3, and
- W is OH or a radical 0 (Ci -Ce-alkyl), and in the presence of a base with an isothiocyanate of the formula (V)
- R 3 has the meaning given above, initially to a thiourea of the formula (II)
- the acetic acid derivative of the formula (III) is therefore already present when the aniline of the formula (IV) reacts with the isothiocyanate of the formula (V) to form the thiourea of the formula (II). It does not affect this reaction negatively and rather has the effect that the thiourea of the formula (II) does not accumulate in the reaction mixture, but is directly further converted to the compound of the formula (I). Consequently, the thiourea of the formula (II) is converted directly in situ the compound of the formula (I) reacted, ie the intermediately formed thiourea of the formula (II) reacts in situ directly further to give 2- (phenylimino) -1, 3-thiazolidin-4-one of the formula (I).
- the compounds of the formula (I) can exist as E or Z isomers or as a mixture of these isomers. This is illustrated by the crossed double bond in formula (I).
- the E isomer is present in each case.
- the Z isomer is present in each case.
- the Z isomer or a mixture of E and Z isomer is present in which the proportion of the Z isomer is greater than 50% and increasingly preferably greater than 60%, 65%, 70% , 75%, 80%, 85%, 90%, 95% based on the total amount of E and Z isomers in the mixture.
- Y 1 and Y 2 independently of one another represent fluorine, chlorine or hydrogen
- R 1 and R 2 independently of one another represent fluorine, chlorine (Ci-C3) alkyl or hydrogen, and
- R 3 for optionally substituted phenyl, (Ci-C 6 ) AIkyI or (Ci-C 6 ) HalogenaIkyI, the substituents being selected from halogen, (Ci-C 6 ) AIkyI, (C3-Cio) CycIoaIkyI, cyano, nitro, Hydroxy, (Ci-C 6 ) alkoxy, (Ci-C 6 ) HalogenaIkyI and (Ci-C 6 ) HalogenaIkoxy, in particular from fluorine, chlorine, (Ci- C3) alkyl, (C3-C6) CycIoaIkyI, Cyclopropyl, Cyano, (Ci-C3) alkoxy, (Ci-C3) HalogenaIkyI and (Ci- C3) haloalkoxy.
- Y 1 and Y 2 independently of one another represent fluorine or hydrogen

- R 3 for CH2CF3.
- the 2- (phenylimino) -l, 3-thiazolidin-4-ones of the formula (I) can be prepared with good yields and in high purity using the process according to the invention.
- the fact that in the process according to the invention the reaction of the aniline of the formula (IV) with the isothiocyanate of the formula (V) in the presence of a base and the acetic acid derivative of the formula (III) can be carried out with high selectivity and yield is surprising because it is known that anilines can be alkylated on nitrogen with acetic acid derivatives of the formula (III) (see for example US20050020645; WO2004 / 039764).
- the process according to the invention allows the use of diluents suitable for the industrial scale, especially those in which voluminous precipitations of the thioureas of the formula (II) can otherwise occur.
- Another resulting benefit for the Process economy is that the process according to the invention enables the desired target compounds to be obtained without the need for complex isolation processes for the intermediate stage.
