실험 절차

To the product of Step A (7.5 g, 20.52 mmol) in dichloromethane (24 mL) was added trifluoroacetic acid (12 mL, 156 mmol) and the mixture stirred for 1 h. The solvent was removed in vacuo and the oil azeotroped with toluene (2×20 mL) to afford the title compound as a tan amorphous solid. LC/MS 266.1 (M+1).
