2050-25-1 , The common heterocyclic compound, 2050-25-1, name is 2-(2-(Benzyloxy)ethoxy)ethanol, molecular formula is C11H16O3, 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.
Step (i): 2-(2-(Benzyloxy)ethoxy)ethyl methanesulfonate (47) MsCI (15.8 mL. 204 mmol) was added to a solution of 2-(2-(benzyloxy)ethoxy)ethanol (46) (25 g, 127 mmol) and Et3N (36 mL, 255 mmol) in DCM (180 mL) at 0C, the reaction mixture was allowed to warm up to RT and stirred for 16h. The reaction mixture was diluted with DCM (50 mL) and washed with water (2 x 50 mL), 1 M HCI (aq.) (2 x 50 mL), the organic layer was dried (MgS04), filtered and concentrated in vacuo to afford 2-(2-(benzyloxy)ethoxy)ethyl methanesulfonate (47) (35 g, 100 %) as an orange oil: m/z 275 (M+H)+ (ES+). 1 H NMR (400 MHz, CDCIs) delta: 7.37-7.27 (m, 5H), 4.55 (s, 2H), 4.40-4.37 (m, 2H), 3.78-3.76 (m, 2H), 3.71-3.68 (m, 2H), 3.64-3.62 (m, 2H), 3.02 (s, 3H).
According to the analysis of related databases, 2050-25-1, the application of this compound in the production field has become more and more popular.
