実験手順

A solution of diethyl 5-[(diethoxyphosphinyl)methyl]-1,3-benzenedicarboxylate (0.186 g, 0.5 mmol) in 12 N HCl (2.5 mL) was heated at 100° C. for 24 hours. The resulting precipitate was washed with water and dried under vacuum to give 0.057 g of white powder (41% yield).

後処理

  1. washThe resulting precipitate was washed with water
