실험 절차

A mixture of 1-(4-hydroxymethyl-phenyl)-ethanone (1 g, 6.67 mmol), 4-formylcinnamic acid (1.17 g, 6.67 mmol) and 1.7 M KOH (5.89 ml) in EtOH (60 ml) was stirred at room temperature overnight. The resulting precipitate was filtered and washed with EtOH to give 1.39 g of (E)-3-{4-[(E)-3-(4-hydroxymethyl-phenyl)-3-oxo-propenyl]-phenyl}-acrylic acid as its potassium salt.

후처리

  1. filtrationThe resulting precipitate was filtered
