1702/1 A) was observed on the HPLC while HPLC was running but no visible halo was found. So now please add linker again. Waiting to see if it is going to give a nice H-NMR signal. Also, spin-diffused bromide did not react with benzyl amine as expected but rather gave back the starting material. She was also unable to isolate or identify the whole mixture while using H-NMR to check for any other reaction between them. So now take only halogenated compound and react it with sodium azide in DMF from time to time. See if you get a nice NMR peak with all carbon peaks or exchange with nitrogen and isolated leaving group to be used as starting material. Going back to another in H-exchange giving an anionized and cationic structure mixture while H-NMR is still running a signal and a visible halo were found. Maybe need to add methyl ether phase (CS, SF 1/2 polarized)
