実験手順

To a stirred solution of 2-(4-(quinolin-2-ylmethoxy)phenyl)acetyl chloride (2.0 g, 6.557 mmol) in DCM (50 mL) was added DMAP (1.4 g, 13.11 mmol) followed by methyl 1-hydroxycyclopropanecarboxylate (1.1 g, 9.836 mmol) under a nitrogen atmosphere at RT. The reaction mixture was stirred for 14 h and after complete consumption of the starting material (by TLC), the reaction mixture was quenched with water (10 mL) and the aqueous layer was extracted with DCM (2×50 mL). The combined organic layers were washed with a saturated NaHCO3 solution (20 mL) and brine (20 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo to afford crude methyl 1(2-(4-(quinolin-2-ylmethoxy)phenyl)acetoxy)cyclopropanecarboxylate (2.0 g) as a solid.
