precedent, we prepared a peptide nucleic acid monomer, possessing 5-hydroxymethyuracil, which was compatible with Fmoc-based oligopeptide synthesis. An improved, large-scale synthesis of 5-hydroxymethylcytosine was developed, as a starting point for the synthesis of a monomer containing this nucleobase. In each case, the hydroxyl group was blocked as a t-butyldiphenylsilyl ether, and the exocyclic amino
