The structures of the products were assigned by NMR, MS, IR etc. The in vitro antitumor activity tests against leukaemia HL-60 and liver cancer BEL-7402 indicated that (R)-ethyl 2-(2-(5-fluoro-2,4- dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamido)-3-(4-hydroxyphenyl) propanoate showed more inhibitory effect against BEL-7402 than 5-FU. Keywords: 5-fluorouracil; amino acid ester; antitumor activity 1. Introduction 5-Fluorouracil (5-FU) is an antimetabolite of the pyrimidine analogue type,
