실험 절차

To a solution of 0.9 g (3.8 mmol) 2-((S)-2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid in 9 ml DMF under argon at room temperature, was added 1.4 g (4.2 mmol) TBTU, 3.3 ml (19.2 mmol) N-ethyldiisopropylamine and finally 0.8 g (3.8 mmol) 5-(tetrahydro-pyran-4-yl)-2,3-dihydro-1H-isoindole (CAS: 905274-50-2). The mixture was stirred at room temperature overnight. The solvent was removed in vacuo. The residue was dissolved in ethyl acetate. The solution was washed twice with water and twice with sat. NaHCO3 solution, dried over Na2SO4, filtered and concentrated in vacuo. The crude oil was purified with flash column chromatography on silica eluting with a gradient formed from heptane and ethylacetate to provide 1.5 g (93%) of the title compound as a yellow oil. MS (m/e): 420.2 [M+H]+.
