실험 절차

To a solution of the product of Example 49-5 (185.0 g, 0.334 mol) in dichloromethane (220 mL) was added 4 M HCl in dioxane (430 mL, 1.72 mol) and the solution was mixed at room temperature for 3.5 h. The reaction was quenched by addition of ethyl acetate (1 L) and pH 7 phosphate buffer (1.5 L) and the layers were separated. The organic layer was concentrated and chased with ethanol to a final volume of approximately 1100 mL. The product precipitated and was isolated by filtration and dried to give the title compound (105.79 g, 70%).
