Selectively herbicidal title compds. (I; R1 = alkyl, alkenyl, halogenoalkyl; R2 = Ph, halogen, CF3, alkyl, alkoxy-substituted Ph or cyclohexyl) were prepd. by reaction of II and III. Thus, 4-ClC6H4NHMe in 100 ml was treated with H2O, then, in 20 min, with 3-ClCO2C6H4NHCO2CH2CHMe2 in AcOEt and K2CO3 in H2O at 10-15≦̸C and the mixt. stirred 30 min at 15≦̸C to give I(R1 = ClC6H4; R2 = Me).
