Abstract
It was established that both 1-(2-hydroxyethyl)uracil and 3-(2-hydroxyethyl)-uracil, which are converted to 1, 3-bis (2-hydroxyethyl) uracil, are formed in the first step of the reaction of uracil with ethylene carbonate. The simultaneous formation of 9- (2-hydroxyethyl) adenine and 3- (2-hydroxyethyl) adenine occurs in the reaction of adenine with ethylene carbonate. The only product of hydroxyethylation of cytosine was 1-(2-hydroxyethyl) cytosine. Methods for the analytical separation of the hydroxyethylation products and the preparative isolation of the 1- and 9-hydroxyethyl derivatives are proposed.
