Procedure

To a solution of EXAMPLE 555A (0.75 g) in dichloromethane (3 mL) was added a few drops of water followed by trifluoroacetic acid (1.19 mL) and the reaction stirred at room temperature. After stirring for 2 hours, additional trifluoroacetic acid (0.5 mL) was added. After an additional 4 hours, the reaction mixture was concentrated and dried under high vacuum. The resulting oily solid was triturated with diethyl ether with sonication. Filtration and washing with diethyl ether gave the title compound as a mixture of cis and trans isomers.
