| Abstract: | Antifolate alimta (1) derived from pyrrolo2,3-d]pyrimidine is a multitargeted antitumor agent and a novel synthetic route to it was established. Ethyl 4-(4-ethoxy-4-oxobutyl)benzoate (5) was prepared via Friedel-Crafts acylation and Huang reduction in 36.6% yield, then alimta was synthesized through selec- tive reduction with KBH4/LiBr, oxidation, ring-closing and etc. in overall yield of 4.8%. |
