Procedure

To a solution of 0.250 g (0.700 mmol) of the product of Example 5 in 1.0 mL of dichloromethane was added 0.5 mL of trifluoroacetic acid and the resulting mixture was stirred for 2 h at room temperature and then concentrated in vacuo. The residue was chromatographed on silica gel eluting with a gradient of ethyl acetate/hexanes (1:3) to (1:1) to provide 0.211 g (100%) of the carboxylic acid as a colorless oil. Electrospray Mass Spec 300.0 (M−H)−
