Tetrahydrofuran → HCID 21840894, compound

Participants

Reaction Steps

To a mixture of 0.21 g (0.9 mmol) of 5-(2-hydroxymethyl-α-methoxybenzyl)-3-methylthiazole, 3 ml of tetrahydrofuran and 0.29 g (1.35 mmol) of 2,3-dichloro-5-trifluoromethylpyridine was added 0.05 g (1.3 mmol) of 60% sodium hydride under ice-cooling and stirred at room temperature for 2 hours. After completion of the reaction, 100 ml of ether was added and washed 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) to give 5-[2-(3-chloro-5-trifluoromethyl-2-pyridyloxymethyl)-α-methoxybenzyl]-3-methylthiazole (0.32 g, 86.1%) as colorless oil.
