Ammonium Chloride → HCID 178444289, compound

Participants

Reaction Steps

Under a nitrogen atmosphere, 4.0 g of 4-(4-(trans-4-pentylcyclohexyl)cyclohexyl)-2-cyclohexenone (r-9) was dissolved into 50 mL of THF, 14.5 mL of butylmagnesium bromide THF solution (1 M/L) was added dropwise thereto at room temperature, and the resultant mixture was stirred at 50° C. for 30 minutes, and then stirred at room temperature overnight. A saturated aqueous solution of ammonium chloride was added dropwise under ice-cooling, the resultant mixture was subjected to extraction with ethyl acetate, and then organic layers were combined, the resultant organic layer was washed with saturated brine, and then dried over anhydrous magnesium sulfate. A solvent was evaporated under reduced pressure, and the resultant residue was purified by fractionation on silica gel column chromatography (eluate:heptane:ethyl acetate=7:3 (in a volume ratio)), and thus 4.70 g of 4-(4-(trans-4-pentylcyclohexyl)cyclohexyl)-1-butyl-2-cyclohexene-1-ol (compound (r-10)) was obtained.
