2-Bromobenzenethiol → HCID 66842178, compound

Participants

Reaction Steps

—Sulfuryl chloride (1.08 ml, 13.4 mmol) was added to a solution of 2-bromobenzenethiol (1.27 g, 6.69 mmol) in dichloromethane (45 ml). The reaction mixture was stirred at room temperature for 15 min. and concentrated under reduced pressure. The resulting material was dissolved in diethyl ether and added dropwise to a solution of [1-(3,5-difluoro-benzyl)-1H-indol-6-yl]-methyl-carbamic acid tert-butyl ester (Example 6, method 1, step i; 2.50 g, 6.71 mmol) in diethyl ether (45 ml). The reaction mixture was stirred for 3.5 h and then poured into a saturated aqueous solution of sodium hydrogencarbonate. The product was extracted into ethyl acetate; the combined organic phases were washed with brine, dried over sodium sulfate and concentrated under reduced pressure. Column chromatography (heptane/ethyl acetate 9:1→8:2) afforded [3-(2-bromo-phenylsulfanyl)-1-(3,5-difluoro-benzyl)-1H-indol-6-yl]-methyl-carbamic acid tert-butyl ester (3.02 g).
