実験手順

To a suspension of 3.2 g (85 mmole) of lithium aluminum hydride in 50 ml of dry tetrahydrofuran was added dropwise, a solution of 8.5 g (28.0 mmole) of 1-(diphenylmethyl)-N-ethyl-3-azetidinecarboxamide in 50 ml of dry tetrahydrofuran. After the addition was complete, the reaction was refluxed for two hours, cooled to room temperature, and decomposed by the successive addition of 3.4 ml of water, 3.4 ml of 15% aqueous sodium hydroxide and 10.2 ml of water, titrating the final water addition to give a granular precipitate. The inorganic precipitate was removed by filtration, washed with tetrahydrofuran and evaporated in vacuo to give 6.7 g of 1-(diphenylmethyl)-N-ethyl-3-azetidinemethanamine as a heavy syrup. This was used without further purification.
