Reaction Steps

To a solution containing the product from Example 160A (0.050 g, 0.195 mmol) in dichloromethane (1.0 mL) was added trifluoracetic acid (1.0 mL), and the mixture was stirred at room temperature for 2 hours. The solvent was evaporated and the residue was triturated with ether to give a white solid, which was collected by filtration and used without further purification.
