Abstract
Precursors for use in the synthesis of polynucleotides and methods of using the precursors in synthesizing polynucleotides are disclosed. The precursors include a heterocyclic base having an exocyclic amine group and a substituted or unsubstituted triaryl methyl protecting group bound to the exocyclic amine group.
