摘要:A method for the solid-phase synthesis of a target oligonucleotide OT is disclosed, wherein said method comprises a step of incubating a nucleoside or oligonucleotide, which is covalently linked to a solid support and comprises a backbone hydroxyl moiety protected by a di(p-methoxyphenyl)phenylmethyl (DMT) protecting group, with a deprotection mixture, thereby cleaving said protecting group from said nucleoside or oligonucleotide, wherein said deprotection mixture is a liquid composition comprising a solvent, a protic acid having a pKa equal to or smaller than 4, and at least one alcohol of Formula (D), wherein in RD-1 R,D-2 R,D-3 RD-4 and RD-5 are indepently of each other selected from the group consisting of H, OH, a e1-e6-alkyl group, O(C1-C6-aIkyl), C(O)(Ci-C6-alkyl), C(O)O(Ci-C6-alkyl), F, Cl, Br, I, and CN. Such a method does not only suppress depurination, but also results in an acceptable product yield.
