Methyl chloroacetate → HCID 59536735, compound

Participants

Reaction Steps

Of the compound from Example 164A, 9.78 g (about 23.32 mmol, purity 75%) were dissolved in 75 ml of acetonitrile. Then 3.55 g (25.65 mmol) of potassium carbonate and 2.46 ml (27.98 mmol) of methyl chloroacetate were added. The mixture was stirred under reflux for 5 hours. After cooling, it was filtered with suction. The filtrate was concentrated a little on a rotary evaporator and then diluted with 30 ml of ethyl acetate and washed with 30 ml each of 1M hydrochloric acid and of saturated aqueous sodium chloride solution. The organic phase was dried over sodium sulphate, filtered and freed from the solvent on a rotary evaporator. The residue was purified by chromatography on silica gel (elution: cyclohexane/ethyl acetate 2:1). This gave 7.1 g (79% of theory) of the title compound.
