| Hazard Information | Back Directory | [Description]
Methoxyacetyl chloride is a acylating reagent; precursor to methoxyketene; in combination with Lewis acids is a reagent for aromatic
chloromethylation. | [Chemical Properties]
clear colorless to yellow liquid | [Uses]
Methoxyacetyl chloride is used as an intermediate for active pharmaceutical ingredients and dyes. Further, it acts as a precursor for the synthesis of agrochemicals. | [Synthesis]
Step 1: To a solution of methoxyacetic acid (20 mL, 0.26 mol) in dichloromethane (170 mL) was added dropwise oxalyl chloride (30 mL, 0.34 mol) and a catalytic amount of DMF (a few drops) at 0 °C. The reaction mixture was stirred at room temperature overnight and the solvent was subsequently removed by rotary evaporator. The residue was distilled under reduced pressure to afford methoxyacetyl chloride (54b, 25.4 g, 90% yield). | [References]
