Reaction Steps
Compound 52 (780 mg, 1.29 mmol) was dissolved in dichloromethane (20 mL) and triethyl silane (0.4 mL). Trifluoromethane sulfonic acid was added dropwise at room temperature. The mixture was then left for 2 h at room temperature. Removal of the solvent gave pure title product (700 mg, 99%) MS (M+H+) 546.
