Groebke–Blackburn–Bienayme reaction has been utilized for the synthesis of new imidazo[1,2‐a]pyrimidine derivatives as novel anticancer agents. The cytotoxic activities of compounds were evaluated against human cancer cell lines including MCF‐7, T‐47D, and MDA‐MB‐231, compared with etoposide as the standard drug. Among the tested compounds, hydroxy‐ and/or methoxy‐phenyl derivatives (6a–c and 6k) with IC50 values of 6.72–14.36 μm were more potent than etoposide against all cell lines. The acridine orange/ethidium bromide double staining and DNA fragmentation studies demonstrated that the cytotoxic effect of 3‐hydroxy‐4‐methoxyphenyl derivative 6c is associated with apoptosis in cancer cells.
