Novel title cpds. have formula: (where R2, R6 = H, F, Cl, CN, CH3 at least one being H or F, R3, R4, R5 = (a) H, halo, CN, CF3, lower alkyl (b) lower alkoxy, lower alkylthio (c) -NO2, -SCN with the condition that when at least one of R3 and R5 is chosen from (b) R4 chosen from (a) other than H or (c) and no more than two of R2, R3, R4, R5, R6 are H or R3 and R5 are chosen from (a), (b) and (c) R4 = -NR7R8, lower alkanoyl, alkylsulphonyl, -SO2-NRR1, with the condition that when R4 = SO2NRR1 or alkanoyl at least one of R3 and R5 is not = H, R = methl, ethyl, phenyl, benzyl, allyl, propargyl, p-chlorophenyl R1 = methyl, ethyl, allyl, propargyl or R and R1 together with the N atom form a heterocyclic R and R1 together with the N atom form a heterocyclic gp. W, R7 R8 = 1-4C alkyl or R7 and R8 together with the N atom form a heterocyclic gp. W, W = morpholino, theomorpholinc, pyrrolo, pyrrolino, pyrrolidino, piperidino, N-(lower alkyl)-piperazino, hexamethyleneimino, thiazolidino, DELTA 3-tetrahydropyridino or piperazino, X = O, S, NH, SO, SO2, -CHOH, CO, Y, Y1 = H, halo, NO2 CN, lower alkyl or loweralkoxy) and also their alkali(ne earth) metal salts. |
