Procedure
26.8 g (0.5 mol) of ammonium chloride were introduced into a 500 ml stirred reactor fitted with nitrogen inlet and separate feed device and suspended in 200 ml of methanol. Over the course of 30 minutes 76.1 g (0.5 mol) of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) were added, where upon the reaction mixture was solubilized. The mixture was stirred for a further three hours and then the solvent was evaporated and the remaining solid dried in vacuo.
