HCID 20058556HCID 20058556, compound

Procedure

A solution of the diamine product of step (b) (4.75 g) in 48% aqueous hydrobromic acid (70 ml) was heated under reflux in an atmosphere of nitrogen for 3.5 hours. The solid which formed on cooling was filtered off and crystallised from ethanol, to give the title compound as the dihydrobromide salt, (3.1 g), mp 227°-228°.
