A series of non-classical antifolates, namely 5-(N-phenylpyrrolidin-3-yl)-2, 4, 6- triaminopyrimidines (25a–i) and 2, 4-diamino-(N-phenylpyrrolidin-3-yl)-6 (5H)- oxopyrimidines (26a, b, c, f, h, i) was synthesized and evaluated for their in vitro cytotoxicity. Reacting aniline derivatives with 1, 4-dibromo-2-butanol gave 1-phenyl-3-pyrrolidinols (19a-– i), which were oxidized to pyrrolidin-3-ones (20a–i). The Knoevenagel reaction of 20a–i ...
