반응 단계

Methyl 2-((S)-6-((R)-7-fluoro-4-(4-hydroxy-2,6-dimethylphenyl)-2,3-dihydro-1H-inden-1-yloxy)-2,3-dihydrobenzofuran-3-yl)acetate (Intermediate 28-29) (138 mg) and 4-(bromomethyl)tetrahydro-2H-pyran (160.3 mg) were suspended in dimethylformamide (5 mL) and potassium carbonate (185.7 mg) was added. The reaction mixture was shaken for 48 h at 60° C. and than directly chromatographed by HPLC on reversed phase. The product fractions are collected and lyophilized to give the title compound. Yield: 117 mg; LC (method 23): tR=2.26 min; Mass spectrum (ESI+): m/z=561 [M+H]+.
