Reaction Steps
A suspension of N-((2S)-1-((2-(3-fluoro-4-hydroxyphenyl)-1,3-benzoxazol-6-yl)oxy)propan-2-yl)acetamide (200 mg), potassium carbonate (161 mg) and ethyl iodide (181 mg) in DMF (5 mL) was stirred at 60° C. for 30 min. The reaction mixture was diluted with ethyl acetate, and washed with saturated brine, and the organic layer was subjected to silica gel column chromatography (NH, ethyl acetate), and the solvent was evaporated. The obtained solid was recrystallized from hexane/ethyl acetate to give the title compound (167 mg).
