3-(3-Methylisoxazol-5-yl) and 3-(pyrimidin-2-yl)-2-styrylquinazolin-4 (3H)-ones 8a–l and 9a, c–e, h–l were synthesized by refluxing in acetic acid the corresponding 2- methylquinazolinones 6 and 8 with the opportune benzoic aldehyde for 12 h. The synthesized styrylquinazolinones 8a–l and 9a, c–e, h–l were tested in vitro for their antileukemic activity against L-1210 (murine leukemia), K-562 (human chronic ...
