실험 절차

A mixture of 1-[5-(tert-butyl-diphenyl-silanyloxymethyl)-4-((2R,6S)-2,6-dimethyl-morpholin-4-yl)-2,3-difluoro-phenyl]-ethanone (Intermediate 9, 7.2 g, 28 mmol) and 4N HCl in dry dioxane (75 mL) was stirred at room temperature for 12 hours. The reaction mixture was treated with cold water (20 mL) and extracted with ethyl acetate (3×50 mL). The combined organic phases combined were dried (Na2SO4) and concentrated. The residue was purified over a silica gel flash column using a gradient of ethyl acetate in pet. ether to give the title compound as yellow solid.
