Diethylcarbamoyl chloride → HCID 68380072, compound

Participants

Reaction Steps

3-Chloro-4-fluorophenol was acylated with diethylcarbamoyl chloride to produce 3-chloro-4-fluorophenyl diethylcarbamate, which was converted to 3-chloro-4-fluoro-2-iodophenyl diethylcarbamate via ortho-metalation followed by treatment with iodine. Basic hydrolysis provided 3-chloro-4-fluoro-2-iodophenol, which was coupled to (2-hydroxyphenyl)boronic acid under Suzuki conditions to give 6-chloro-5-fluorobiphenyl-2,2′-diol. Copper-mediated cyclization provided 4-fluorodibenzo[b,d]furan-1-ol.
