Reaction Steps
To a solution of Intermediate 112 (729 mg, 1.38 mmol) in dichloromethane (10 mL) was added trifluoroacetic acid (2133 μl, 27.69 mmol). This solution was slightly darker after addition. The reaction was placed under a nitrogen atmosphere and stirred until LCMS analysis indicated consumption of starting material (˜45 minutes). At that time, solvent was removed in vacuo. The residue was taken up in toluene and sonicated, and then toluene was removed in vacuo. This was repeated twice, affording an orange solid of high purity by proton NMR. The product was taken forward without further purification.
