Procedure
Compound 22 (500 mg, 1.71 mmol) was dissolved in dry DCM (6 mL). Trifluoroacetic acid (0.66 mL, 8.58 mmol) was then added to the solution at 0° C. and stirred under nitrogen for 1 h. The reaction mixture was then concentrated under vacuum and used directly in the next step without further purification.
