Dimethylcarbamoyl Chloride → HCID 86710036, compound

Participants

Reaction Steps

3-Cyclohexyloxymethyl-2-isopropylimidazo[1,2-a]pyridine-7-thiol (210 mg, 0.691 mmol) obtained in step 1 was dissolved in 1,2-dichloroethane (2.0 mL). Under ice-cooled condition, triethylamine (0.140 mL, 1.00 mmol) and dimethylcarbamoyl chloride (0.0770 mL, 0.834 mmol) were added, and the mixture was stirred at room temperature for 30 minutes. After adding a saturated sodium hydrogen carbonate aqueous solution to the reaction mixture, the reaction mixture was filtered through a Presep (registered trademark; diatomaceous earth, granular type M, 4.5 g/25 mL). The solvent was then evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=70/30) to give S-3-(cyclohexyloxymethyl)-2-isopropylimidazo[1,2-a]pyridin-7-yl dimethylthiocarbamate (121 mg, yield 47%).
