Participants

Reaction Conditions

Reaction Steps

To 0.25 g (1 mmol) of 5-(2-chloromethyl-α-methoxybenzyl)-3-methylthiazole, 2 ml of N,N-dimethylformamide, 0.28 g (2 mmol) of potassium carbonate and 0.33 g (2 mmol) of 2,5-dichlorophenol were added and stirred at 80° C. for 3 hours. After completion of the reaction, 100 ml of ether was added and washed twice with 80 ml of brine. The ether layer was dried over anhydrous magnesium and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (ethyl acetate/n-hexane) and recrystallized from ether/n-hexane to give 5-[2-(2,5-dichlorophenoxymethyl)-α-methoxybenzyl]-3-methylthiazole (0.28 g, 74.0%) as colorless crystals. mp. 78.5-79.5° C.
