合成路线1
该中间体在本合成路线中的序号：(III)Lithiation of 1-(ethoxymethyl)-5-isopropyl-2-thiouracil (I) by means of LDA in cold THF, followed by condensation with 3,5-dimethylbenzaldehyde (II) gave the 6-(alpha-hydroxybenzyl) derivative (III). Oxidative hydrolysis of the thione function of (III) with H2O2 afforded the corresponding uracil (IV). Acetylation of (IV) with Ac2O in pyridine provided acetate ester (V), which was subjected to hydrogenolysis in the presence of Pd/C to furnish the title benzyl derivative.
