=Objective= Isolating the "demethylated" product of the reaction of furan containing Ugi products with TFA, as [|explained here]. =Steps=
 * 1) Dissolve 50 mg of Ugi product (for example 62E) 500 ul CDCl3 and take H NMR
 * 2) Add 500 ul TFA, mix and take NMR after 5 mins
 * 3) Monitor by NMR after approximately 10, 20, 40, 80, etc. min until the reaction is complete (should be around 48 hours)
 * 4) Pour into 10 ml of 10% NaOH and 10 ml of methylene chloride. Verify that the water layer is basic using pH paper.
 * 5) Wash twice with 10 ml of methylene chloride then combine all the organic phases.
 * 6) Add MgSO4 until fluffy when stirred, filter and evaporate.
 * 7) Get the weight and take NMR.
