Workup

  1. 1
    ExtractionThe resulting mixture was extracted with EtOAc (200 ml×2)
  2. 2
    DryingThe combined extracts were dried over anhydrous sodium sulfate
  3. 3
    Concentrationconcentrated

Procedure

Saturated aqueous potassium carbonate (190 mL) and 4-methoxybenzoyl chloride (60.8 g, 358 mmol) were added to a solution of glycine methyl ester (30.0 g, 239 mmol) in THF (100 mL) at 0° C. The reaction mixture was stirred for 3 h at 0° C. and then poured into water (100 mL). The resulting mixture was extracted with EtOAc (200 ml×2). The combined extracts were dried over anhydrous sodium sulfate and concentrated to afford methyl 2-(4-methoxybenzamido)acetate (46.2 g, 86% yield) as a colorless solid, which was used directly without further purification.
