The present invention is a process for the preparation of 2′-deoxy-5-trifluoromethyl-β-uridine characterized in that a 5-trifluoromethyyl-2,4-bis(triorganosilyloxy)pyrimidine and a 1-halogeno-2-deoxy-alpha-D-erythro-pentofuranose derivative are subjected to a condensation reaction to give a 1-(2-deoxy-β-D-erythro-pentofuranosyl)-5-trifluoromethyluracil derivative which is then subjected to a deprotection reaction to give 2′-deoxy-5-trifluoromethyl-β-uridine.
