Abstract A novel series of 2-amino-4-(coumarin-3-yl)-6-substituted phenyl pyrimidines (5a– h) were synthesized from 3-acetylcoumarin (3). The structures of the synthesized compounds were elucidated by IR, 1 H NMR, 13 C NMR, and Mass spectroscopic techniques. The synthesized compounds were screened for in vivo analgesic activities at a dose of 20 mg/kg body weight (bw). Among them, compounds 5b and 5h exhibited ...
