The reaction mixture is stirred for 1.5 hours and then quenched with water. The resulting mixture is filtered through a pad of celite and the pad then washed with methanol and methylene chloride. The filtrate is dried over sodium sulfate, then filtered and concentrated to obtain (2RS,12bSR)-2-aminomethyl-2-(2-propenylamino)-1,3,4,6,7,12b-hexahydro-2H-benzofuro[2,3-a]quinolizine.
