or with 3 ′-amino-3 ′-deoxy-5 ′-O-DMT-β-thymidine followed by desilylation of the protected dimers. The 3 ′-O-phosphoramidite derivative of one of the nucleoside dimers was successfully prepared by condensation with [P(-Cl)(-OCH2CH2CN)-N(iPr)2}] in DCM in the presence of N,N-diisopropylethylamine (DIPEA), which is a building block for the preparation of mercaptoacetamido-linked oligonucleotides of therapeutic
