Started 03/12/13 6pm Used 80 mg crude sample of AEW 102-2 (the rest was submitted to HMBC and HMQC overnight)

Crude AEW 102-2 (~80 mg) was dissolved in MeOH (1 mL) and a few drops of H2SO4 was added and the reaction mixture stirred at 80 ˚C for 14 hours. TLC showed no SM. Reaction mixture poured over water 5 mL and extracted with EtOAc (10 mL x 2), combined organic layers dried over MgSO4, filtered and evaporated to give a red pale red/brown oil. NMR shows pretty clean product - matches CRO spectra.

Purified by filtration through a column containing silica, eluent EtOAc to give the desire product as a pale brown oil 50 mg.

Data:

TLC (30% EtOAc in hexane)
