or CHPh; or Y is a carbonyl (C═O) and X is chosen from the following groups: NH, N-Ph, N-(2-Py), N-(3-Py), N-(4-Py), N-2-pyrimidyl or N-5-pyrimidyl.
本发明涉及一种制备式(II)的2-氨基噻唑衍生物的方法:
其中,若Y为亚甲基(CH2),则X可从以下基团中选择:O、NH、(C1-C4)N-烷基、N—Bn、N-Ph、N-(2-Py)、N-(3-Py)、N-(4-Py)、N-2-嘧啶基、N-5-嘧啶基、S、SO、SO2、CH2或CHPh;
若Y为羰基(C═O),则X可从以下基团中选择:NH、N-Ph、N-(2-Py)、N-(3-Py)、N-(4-Py)、N-2-嘧啶基或N-5-嘧啶基。
