Reaction Steps
To a cooled (0° C.) and stirred solution of Compound 30 (0.5 g, 1.04 mmol) in dry DCM (10 mL) was added hydrogen chloride [4M in 1,4-dioxane] (5.2 mL, 20.8 mmol). The mixture was warmed to ambient temperature and left to stir overnight (with a calcium chloride drying tube). The reaction solvents were removed under reduced pressure, and the residue was azeotroped twice with methanol and diethyl ether to give the title compound as a white solid in quantitative yield. LCMS (+ESI) m/z 379.36 [M+H]+.
