Title compds.(I; R1,R2 = Me, Et; Y = H, F, Cl, Br, MeO, Me, Et, CF3; Ar = 2-thiazolyl, 5,6-dehydro-4H-cyclopentadiazol-2-yl, 2-pyridyl, 4-pyrimidyl, 2-oxazolyl, 2-benzoxazolyl, phenyl) were prepd. by reaction of II(R5,R6 = C1-3 alkyl, forming piperidino, pyrrolidino, morpholino, N-methyl piperazino with N) and III followed by acid hydrolyzation. Thus, aniline in THF was added to II(R1,R2 = Me; R5,R6 = forming pyrrolidinyl with N; Hal = Cl; Y = H) at -40≦̸C and the temp. of the mixt. was increased to room temp. followed by stirring for 24 hr and extracting to give I(R1,R2 = Me, Ar=Ph, Y=H).
