Reaction Steps

2-Chloro-quinolin-5-ol (CAS 124467-35-2) (0.3 g, 1.56 mmol) was dissolved in acetone (10 mL) and potassium carbonate (0.368 g, 2.75 mmol) was added. After addition of 2-bromethylmethylether (0.25 ml, 2.7 mmol) the reaction mixture was stirred for 18 h at 50° C. Then water was added and the mixture was extracted with ethyl acetate (3×). The combined organic phases were dried, filtered and concentrated. The residue was subjected to column chromatography (silica gel, heptane/ethyl acetate 9:1/4:1) to yield 2-chloro-5-(2-methoxy-ethoxy)-quinoline as a colourless oil (0.12 g, 30%).
