5'-O-Dimethoxytrityl-2'-O-tetrahydropyranylnucleosides (2) smoothly reacts with 4-chlorophenyl 5-chloro-8-quinolyl phosphorochloridate (1) prepared form 4-chlorophenyl phosphodichloridate and 5-chloro-8-hydroxyquinoline to give 5'-O-dimethoxytrityl-2'-O-tetrahydropyranylnucleoside 3'-(4-chlorophenyl, 5-chloro-8-quinolyl) phosphates (3) in high yields.They are key intermediates for the synthesis of oligoribonucleotides via phosphotriester approach.
