Procedure

Into a Round bottom flask was added compound 21 (250.0 mg, 0.0006118 mol) and Tetrahydrofuran (5.0 mL, 0.062 mol) and Tetra-n-butylammonium fluoride (190 mg, 0.00073 mol). The reaction mixture was stirred at room temperature for 30 minutes. The reaction mixture was poured into water, extracted with EtOAc. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified with biotage to give product 22 (55 mg).
