Reaction Steps

A solution of 4 g (18.2 mmol) of 8-benzyl-2-oxa-5,8-diazabicyclo[4.3.0]nonane in 100 ml of methanol and 3.5 ml of concentrated hydrochloric acid is hydrogenated on 2 g of palladium-on-active charcoal (10% of Pd) at 80° C. under 100 bar. The catalyst is filtered off and washed with water. The filtrates are concentrated and the product is crystallized by trituration with a little methanol. The crystals are filtered off with suction, washed with acetone and dried in air.
