| 摘要 |
The present invention relates to a process for preparing 2-amino-thiazoline derivatives of formula (II): in which either Y is a methylene (CH<SUB>2</SUB>) and X is chosen from the following groups: O, NH, (C1-C4) N-Alkyl, N-Bn, N-Ph, N-(2-Py), N-(3-Py), N-(4-Py), N-2-pyrimidyl, N-5-pyrimidyl, S, SO, SO<SUB>2</SUB>, CH<SUB>2 </SUB>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.
