Procedure

To a stirred solution of ethyl 2-(4-hydroxyphenyl)acetate (20 g, 111.10 mmol) in AcN (200 mL) were added K2CO3(145.9 g, 333.30 mmol) and 2-(chloromethyl) quinoline (28.50 g, 133.32 mmol) at RT. The reaction mixture was heated at 90° C. for 12 h and then cooled to RT and filtered. The filtrate was concentrated in vacuo. The residue was then diluted with water (100 mL) and extracted with EtOAc (3×100 mL). The combined organic layers were washed with water, a saturated NH4Cl solution, and then dried over anhydrous Na2SO4, filtered and concentrated in vacuo to afford ethyl 2-(4-(quinolin-2-ylmethoxy)phenyl)acetate (38.0 g, 89%) as a solid.
