3.1.6. General Procedure for the Synthesis of Conjugates **10**

ADP (*n*-Bu3N salt, 0.02 mmol) was dissolved in dimethyl sulfoxide (DMSO) (0.2 mL) and activated as described above for morpholino nucleotides **3A-ClU**. In 1 h, a solution of 2'-aminomethylmorpholino nucleosides **7A-ClU** (0.06 mmol) in DMI (0.2 mL) and *n*-Bu3N (0.06 mmol, 0.014 mL) were added to the reaction mixture. In 3 h, the reaction was completed. Further treatment of the reaction mixture, deblocation and purification of target conjugates **10A-ClU** were carried out as described for conjugates **4A-ClU**.
