4,4-diphenylbutanenitrile

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a suspension of lithium aluminum hydride (23 g) in ether (1 L) is added a solution of 4,4-diphenylbutyronitrile in dioxane (6.25 L), dropwise, at a rate causing gentle reflux. The reaction is maintained at reflux for one hour, and then a solution of potassium carbonate (200 g) in water (300 mL) is added dropwise with stirring. The mixture is filtered with a 1/1 dioxane/ether wash, and evaporation in vacuo of the filtrate followed by distillation affords the title compound (76 g), bp 145°-150° C. at 0.6 mm. The free amine is generally converted to the hydrobromide salt prior to use. The reaction is maintained at reflux for one hour The mixture is filtered with a 1/1 dioxane/ether wash evaporation in vacuo of the filtrate followed by distillation
