Reaction Steps

To a suspension of lithium aluminum hydride (0.95 g, 25.0 mmol) in dry THF (40 ml) was added dropwise at room temperature while stirring a solution of 7-oxo-3,9-dimethyl3,9-diazabicyclo[3.3.1)nonane (2.78 g, 16.5 mmol) in dry THF (50 ml). After stirring at room temperature for 4.5 hrs, water (1 ml), 40% aqueous sodium hydroxide solution (1 ml) and water (3 ml) were added successively to a reaction solution. Further anhydrous magnesium sulfate was added and stirred, and thereafter the reaction was filtered. The filtrate was concentrated under reduced pressure to afford the title compound (2.62 g) as an oily product.
