To a solution of #27 (500 mg, 0.723 mmol) in dichloromethane (7 mL, 0.1 M) was added trifluoroacetic acid (3 mL). The reaction mixture initially became orange, then darkened over time. After stirring for 18 hours, the solvent was removed in vacuo to give #28 (460 mg, quantitative) as a dark brown glass, which was used without further purification. LC-MS: m/z 636.3 [M+H+].
