A novelpeptide nucleic acid (PNA) monomer 16 containing a novel 1-methyl-6-mercaptopurine base was synthesized by coupling the in situ generated acid chloride of (1-methyl-6-mercaptopurin-9-yl)acetic acid (6) into an L-lysine backbone (13) using 10% CCl4 in pyridine and Ph3P. Compound 6 was synthesized from 6-mercapto-1-methylpurine and ethylbromoacetate in the presence of NaH followed by alkaline
