Reference of 14869-41-1, These common heterocyclic compound, 14869-41-1, name is 2-(2-Chloroethoxy)acetic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
In a glass RBF equipped with a Teflon-coated magnetic stirrer was dissolved 4-fluoro-2-methoxy-5- nitro-phenylamine (1 eq.) in DMF (0.32 M). To this was then added sequentially HATU (1.2 eq.), DMAP (0.1 eq.), (2-chloro-ethoxy)-acetic acid (1.1 eq.) and finally ethyl-diisopropylamine (3 eq.). When the reaction was deemed to be complete by LCMS (14 h), the reaction mixture was diluted with EtOAc and washed sequentially with 10percent aq. HC1, sat. aq. NaHCO3, water and brine. The organic extract was then dried over MgSO4 and filtered. Concentration of the filtrate thus obtained in vacuo furnished the desired product as a tan solid (99percent yield).
The synthetic route of 14869-41-1 has been constantly updated, and we look forward to future research findings.
