Versuchsvorschrift
Starting from 6.58 g (24.8 mmol) of 1-amidino-4,4-diethyl-2-oxoimidazolidine hydrobromide (comp. III: R1, R2 =C2H5 ; R3 =H as hydrobromide) and 3.87 g (26.1 mmol) of diazabicycloundecene (DBU) as auxiliary base and 7.40 g (24.8 mmol) of a compound IV (R4 =CH3 ; R5, R6 =H; R7 =C3H5) by the procedure described in Examples 82-84, 3.94 g (=36.4% yield) of pure 1-cyano-1-[N-methyl-N-(3-trifluoromethylphenyl)carbamoyl]-2-[imino(4,4-diethyl-2-oxo-1-imidazolidinyl)methylamino]ethene (comp. II: R1, R2 =C2H5 ; R3, R5, R6 =H; R4 =CH3) were obtained, melting point 184°-87°.
