The present invention provides an amidite compound represented by formula (1) which enables a synthesis of RNA with high purity, and the method for preparing a polynucleotide by using the same compound. (In the formula (1), wherein R represents the following formula (wherein R
a
and R
b
are identical to or different from each other and each represents a methyl group, an ethyl group, or a hydrogen atom, with the proviso that R
a
and R
b
does not represent a hydrogen atom, n is an integer of 1 to 5), and B
a
represents a group containing optionally protected nucleobase structure, and G
1
and G
2
are identical to or different from each other and each represents a protecting group for a hydroxy group, and G
3
are identical to or different from each other and each represents an alkyl group.
本发明提供了一种由式(1)表示的酰胺化合物,该化合物使RNA合成具有高纯度,并且提供了利用该化合物制备多核苷酸的方法。(在式(1)中,其中R代表以下式(其中Ra和Rb彼此相同或不同,每个代表甲基基团、乙基基团或氢原子,但要求Ra和Rb不代表氢原子,n为1至5的整数),B代表含有可选择保护的核碱基结构的基团,G1和G2彼此相同或不同,每个代表羟基的保护基团,G3彼此相同或不同,每个代表烷基基团。)
