"The reaction of 1-(4-anilino) morpholine/piperidine (I) with carbon disulfide, chloroacetic acid and hydrazine hydrate in ethanol yielded 4-(N-morpholino/piperidino)- phenylthiosemicarbazide (II) which on condensation with carbonyl compounds such as benzaldehyde, isatin, N-methylisatin furnished (VI),(VII) and (VIII) respectively. Treatment of (II) with sodium nitrite and hydrochloric acid afforded 5- 4-(N-morpholino) -anilino- 1,2,3,4 thiatriazole (IX). (I Jon condensation with ethyl chloroacetate followed by reaction with hydrazine hydrate afforded (III) which when treated with isatin, and N-methyl isatin, yielded (IV) & (V) respectively. 2-Methyl-3(4-N-morpholino/piperidino)phenyl-4-quinazolinones (X) and 2-styryl-3-[4-NmorpholiinolpiperledinolJ Phenyl-4- quinazolinones (XI) were also designed using 1."
