Methyl anthranilate to Oil of wintergreen F336. What reactions are taking place?

Part of the F336 Aspirin synthesis independant investigation. I already know how to do the synthesis from ocr_37830_sm_gce_ex_start_sheet but don't understand which reactions are actually taking place, what is being formed and why things like ice and urea need to be added during the reaction.
Also, don't know how to obtain a pure product in the end? :s-smilie:

I don't have the sheet that you are talking about BUT...

... your synthesis involves transforming the amine group on a benzene ring into a hydroxy group.

Strikes me that the easiest way to do this is to go via the diazonium salt, prepared by adding an iced mixture of sodium nitrite and HCl to the methyl anthranilate and then allowing the mixture to warm up.
Hi im doing the same reaction...
did you find anything out about this?
