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. Recommanded Product: 2-(2-Chloroethoxy)acetic acid
In a three-necked round-bottom flask under nitrogen atmosphere equipped with a mechanical stirrer, a thermometer, a condenser and a dropping funnel 6.87 g (0.05 mol) phosphorus trichloride and 10.75 g (0.05 mol) Amberlyst-15 (hydrogen form, dry) were mixed with 50 ml chlorobenzene . Slowly 6.90 g of (0.05 mol) 5-chloro-3- oxapentanoic acid was added drop-wise. After completed addition the reaction mixture was heated to 50 °C for 4 h. During the addition and reaction time the evolution of CO was observed. Then 10 ml water was added and the Amberlyst- 15 was filtered off. The solution was analyzed by ChiEta- and 31P-NMR spectroscopy and 4-Chloro-2-oxabutanyl-l-phosphonic acid observed at 58.9 percentw/w.
The synthetic route of 2-(2-Chloroethoxy)acetic acid has been constantly updated, and we look forward to future research findings.
