To a solution of compound 37-k (300 mg, 0.61 mmol) in DCM (5 mL) was added trifluoroactic acid (2.5 mL) dropwise. The mixture was stirred overnight at room temperature. The reaction mixture was evaporated to dryness to give compound 37-m, which was used in the next step without further purification.
