Summary:The present invention is directed to novel compounds of the formula WHICH COMPOUNDS ARE USEFUL AS HERBICIDES. In the above and succeeding formulae herein, R1 represents hydrogen or R2, and each R2 independently represents loweralkyl of C1-C4, loweralkenyl of C3-C4, loweralkynyl of C3-C4, or radical of the formula -CH2-CH2(CH2)nY wherein n represents 0 or 1, and Y represents methoxy, cyano, bromo, or chloro, subject to the limitation that the groups represented by R1 and R2 together contain from 2 to 8, both inclusive, carbon atoms; R3 represents hydrogen or methyl; and each R4, if taken separately, represents propyl, or both R4, if taken together, jointly constitute with the nitrogen atom an aziridine, pyrrolidine, piperidine, hexahydroazepine, morpholine, or piperazine ring, or such ring bearing mono- or diloweralkyl substitution of a total of not more than 3 carbon atoms.
