Sulfuric Acid → HCID 22063477, compound

Participants

Reaction Steps

4.9 mL concentrated sulfuric acid are added dropwise at 5° C.–15° C. to 1.5 g (31 mmol) sodium cyanide in 5 mL glacial acetic acid. Then the mixture is combined with 3.9 g (24 mmol) of 1-fluoro-2-methyl-4-(2-methylpropenyl)benzene, dissolved in 10 mL glacial acetic acid, and stirred for 1 hour at 50° C.–60° C. The reaction mixture is diluted with ice water, made alkaline with concentrated sodium hydroxide solution, and extracted with dichloromethane. The organic phase is dried with sodium sulfate and freed from solvents in vacuo. The slightly yellow oil thus obtained is further reacted directly. Yield: 4.3 g (87%).
