Reaction Steps

A mixture of the ester from step (a) above (1.77 g, 6.9 mmol) and 5N NaOH (4 mL) in THF/MeOH (20 mL/30 mL) mixture was stirred at room temperature for 16 h. The organic solvent was removed in vacuo, the aqueous solution was acidified with 10% HCl to pH˜2 and then lyophilized to give the title compound, which was used in the next step without additional purification. MS (ESI, pos. ion) m/z: 241 (M+1).
