Participants

Reaction Steps

The product from step (i) was taken up in toluene (3 ml) and methanol (1 ml) and TMS-diazomethane (0.6 ml, 2M in diethylether) added, the mixture stirred at RT for 3 h then evaporated under reduced pressure. The residue was taken up in THF (2 ml) and methanol (1 ml) then 3M NaOH (2 ml) added and the mixture stirred at RT for 2 h. The mixture was then acidified to pH 2 and extracted with ethyl acetate. The organics were dried (MgSO4), evaporated under reduced pressure and then passed onto a Varian NH2 resin (eluting with ethyl acetate, acetonitrile, methanol, DCM then 20% acetic acid in DCM). The acidic fraction was evaporated under reduced pressure and then purified by RPHPLC to give a white solid.
