Ethanol → HCID 178442568, compound

Participants

Reaction Steps

1.78 g (6.5 mM) of 2-octylindan-5-boronic acid, 2.0 g (6.5 mM) of 4-(trans-4-pentylcyclohexy)phenyl bromide, 4 ml of ethanol, 8 ml of benzene, 8 ml of 2M-sodium carbonate aqueous solution and 0.24 g of tetrakis (triphenylphosphine) palladium (O) were mixed and heat-refluxed for 5 hours under stirring. After the reaction, the reaction mixture was poured into ice water, followed by extraction with toluene, washing with water and drying with anhydrous sodium sulfate. Then, the sodium sulfate was removed from the mixture and the resultant mixture was evaporated to obtain a residue. The residue was purified by silica gel column chromatography (eluent: hexane) and recrystallized from a mixture solvent (toluene/methanol) to obtain 1.52 g of 2-octyl-5-[4-(trans-4-pentylcyclohexyl)phenyl]indan (Yield: 51.0%). ##STR310##
