Versuchsvorschrift
To a solution of 2-(4-(quinolin-2-ylmethoxy)phenyl)acetic acid (2.0 g, 0.006 mol) in acetonitrile (200 mL) were added TEA (1.74 mL, 0.01 mol), and 2-bromo-1-(pyridin-3-yl)ethanone (3.42 g, 0.017 mol) under an inert atmosphere. The reaction mixture was then stirred at RT for 16 h, concentrated in vacuo and the residue was extracted with EtOAc (2×100 mL). The combined organic layers were washed with water, dried over Na2SO4, filtered, and concentrated in vacuo to obtain the crude product. The crude material was purified via silica gel column chromatography to afford 2-oxo-2-(pyridin-3-yl)ethyl 2-(4-(quinolin-2-ylmethoxy)phenyl)acetate (1.5 g, 54%) as a solid.
