摘要:
A process for the manufacture of imidazolylvinyl ethers of the formula ##STR1## wherein Im represents the substituted or unsubstituted 1-H-imidazol-1-yl group and An, R and Y are defined hereinbelow by condensation of a corresponding ketone of the formulaAr--CO--CHR--Im (II)with the splitting-off of a Z group, with a condensable substance of the formulaZ--Y (III)in the aqueous solution of a strong inorganic base, preferably in concentrated aqueous soda lye. The reaction may also be carried out in the presence of a second liquid organic phase, preferably benzene or toluene, especially in the presence of a phase transfer catalyst in this case. Through careful crystallization of the product manufactured according to this method, it is possible to manufacture approximately pure E-isomers of the imidazolylvinyl ether of formula (I), without the requirement of chromatographic separation.
