A method of synthesising a compound of formula (I): wherein R
N1
and R
N2
are independently selected from hydrogen, an optionally substituted C
1-7
alkyl group, C
3-20
heterocyclyl group, or C
5-20
aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; from a compound of formula (III): comprising the steps of: (a) removing the allyl group from the compound of formula (III) with appropriate reaction conditions to yield a compound of formula (II): and (b) reacting the compound of formula (II) with a triflating agent to yield a compound of formula (I).
一种合成公式(I)化合物的方法:其中RN1和RN2分别选自氢、可选择取代的C1-7烷基、C3-20杂环基或C5-20芳基,或者与它们所连接的氮原子一起形成一个具有4到8个环原子的可选择取代的杂环环;从公式(III)化合物开始,包括以下步骤:(a)使用适当的反应条件去除公式(III)化合物的烯丙基,得到公式(II)化合物;(b)将公式(II)化合物与
三氟甲烷磺酰化试剂反应,得到公式(I)化合物。
