Procedure

To a solution of unsaturated tert-butyl ester (0.0627 mmol, the title compound of Example 3229) in 2 mL of CDCl3 at room temperature is added 0.5 mL of TFA, and the progress of the reaction is monitored by 1H NMR. The resulting yellow solution is stirred at room temperature until the reaction is complete. The mixture is concentrated in vacuo. The crude product is purified to give the title compound of Example 3230.
