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?

It's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.

They've got over 181,000+ coursework, essays, homeworks etc.. all written by GCSE, A Level, University and IB students across all topics. You get access either by publishing some of your own work, or paying £4.99 for a month's access. Both ways give you unlimited access to all of the essays.

All their documents are submitted to Turnitin anti-plagiarism software, so it can't be misused, and the site's used by hundreds of thousands of UK teachers and students.

What's more, you can take a look around the site and preview the work absolutely free. Click here to find out more...

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?
