The layers were separated, the aqueous layer was extracted with DCM, and the combined organic fractions were dried over MgSO4, filtered and concentrated. The cmde material was dissolved in TFA (2 mL) and heated to 80 °C for 20 minutes. The reaction mixture was then cooled to room temperature,concentrated, and basified by adding aqueous NaHCO3 solution. The crude material was directly purified by a silica gel column to afford the desired product (8 mg, 29%) as a racemic mixture. The product was then separated with chiral HPLC using a chiral column (Phenomenex Lux Sum Cellulose-4, 21. lx2SOmm) and 40% EtOH in Hexanes (20 mL/min) solvent system. Peak 1 was isolated, and further purified usingpreparative LC/MS (pH = 2, acetonitrile/water with TFA) to give the desired product as a TFA salt.
