A solution of 4-methoxy-9-aza-tricyclo[6.3.1.0*2,7*]dodeca-2,4,6-triene (0.50 g of oxalate salt) in hydrobromic acid (48% in water, 10 mL) is stirred at reflux temperature for 3 h. Then, the solution is concentrated under reduced pressure and the residue is azetropically dried using toluene and ethanol. The residue is washed with acetone and dried to give the product as a solid.
