Procedure
To a solution of Example 75D (336 mg, 1 mmol) in tetrahydrofuran (20 mL) heated at 40° C. with an oil bath was added dropwise with an addition funnel a solution of pyridinium tribromide (352 mg, 1.1 mmol) in tetrahydrofuran (20 mL) over 10 minutes. The reaction mixture was heated for an extra 2 hours, and was cooled, filtered, and the filtrate was evaporated to afford the title compound. MS (ESI−) m/z 212.9 (M−H)−.
