Synthesis of New 3-Substituted Quinazolin-4(3H)-one Compounds Via Linking of Some Five-Membered Ring Heterocyclic Moieties With Quinazolin-4(3H)-one Nucleus
2021
Journal of education and science
In this research new compounds containing quinazolin-4(3H)-one nucleus linked to heterocyclic moieties were synthesized using ethyl (4'-oxoquinazolin-3'-yl) acetate (2) as a synthon. This compound was synthesized via 4-quinazolinone's (1) reaction with ethyl chloroacetate in the existence of K2CO3 as a base and acetone as a solvent. The ethyl α-(4'-oxoquinazolin-3'-yl) acetate (2) was converted to the corresponding hydrazide through its reaction with hydrazine hydrate (85 %). Compound (3) was
