Purification was carried out using preparative LC-MS under low pH conditions. The resulting product fractions were concentrated under reduced pressure to give aqueous solutions which were extracted with ethyl acetate. The organic extracts were dried over MgSO4, filtered and concentrated under reduced pressure to afford the title compound;
