実験手順

10.0 g (4.22 [sic] mmol) of 2-hydroxy-3,3-diphenylbutyronitrile were dissolved in 500 ml of methanol (abs.) and, at 5-10° C., HCl was passed in for 3 hours. The mixture was then stirred at 5° C. for 3 hours and at room temperature for 16 hours. Then 200 ml of 6 molar HCl were added and the mixture was evaporated to dryness under reduced pressure. The crude product was recrystallized from an ethyl acetate/heptane mixture. 2.5 g (23%) of 2-hydroxy-3,3-dihenylbutyramide were obtained as a white solid.
