Procedure
The product of STEP 9 (0.254 g, 0.54 mmol) was dissolved in 10 ml methanol and 10 ml 1 N sodium hydroxide solution. The reaction was stirred at room temperature for 18 h, and acidified with trifluoroacetic acid (5 ml). Solvents were evaporated and residue was purified on HPLC using acetonitrile gradient 10-50% in 30 min to yield 0.213 g. NMR spectra of the product were consistent for the proposed structure. FAB-MS:(M+2)=441.3.
