Procedure

A solution of 3-benzyl-2,4-dioxo-8-methyl-3,8-diazabicyclo (3.2.1)octane (2.05 g, 8.91 mmoles) in dry ether (100 mL) was treated gradually with lithium aluminum hydride (1.52 g, 4 mmoles), heated under reflux for one hour, and hydrolyzed successively with 50 mL of water-saturated ether and then 10 mL of water. This mixture was filtered on a celite pad. The filtrate was dried over magnesium sulfate and then evaporated to give the crude titled product which was used without any purification for further uses.
