실험 절차

Compound 35 (700 mg, 1.48 mmol, 1 equiv) was dissolved in dioxane (8 mL). A solution of hydrogen chloride in dioxane (4 mL of a 4 N solution in dioxane, 16 mmol, 10.7 equiv) was added and the reaction was stirred at room temperature overnight. The reaction was diluted with diethyl ether (20 mL) and the resulting solids were collected by filtration under a stream of nitrogen. The product was further dried in a vacuum oven to yield 36 (550 mg, 88% yield) as an off-white solid.
