Participants

Procedure

0.7 g of N3 -(benzyl)-3,8-diazabicyclo[4.3.0]non-1(6)-ene hydrobromide, prepared in Preparation 10, was dissolved in 20 ml of 5% aqueous acetic acid solution. 0.5 g of 10% palladium chracoal in this solution was suspended and the reaction mixture was refluxed under the hydrogen stream for 7 hours. The solid was filtered off. The filtrate was concentrated under reduced pressure and dissolved in 10 ml of 48% bromic acid. By concentrating the solution under reduced pressure again, 0.5 g of the title compound was obtained (yield 73%).
