Versuchsvorschrift
Benzhydrol (20 g, 0.1087 mole) and ethyl acetoacetate (13 g, 0.1 mole) were heated together to 170° and the ethanol so formed removed by distillation. Fractional distillation at 1.0 mm Hg yielded 10.5 g, 39% of benzhydryl acetoacetate as a colourless liquid which later solidified, melting point 44°-54°.
