Toluene → HCID 178444454, compound

Participants

Reaction Steps

A mixture of 19 g of 1-butyloxy-4-[4-(trans-4-pentyl-cyclohexyl)-1-butenyl]benzene (cis/trans mixture), 200 ml of absolute toluene and 100 ml of absolute ethyl acetate: was treated with 2 g of palladium/carbon (10%) and hydrogenated at normal pressure and room temperature until the hydrogen uptake came to a standstill. The inorganic material was removed by filtration and the filtrate was concentrated. The residue was purified by chromatography on silica gel with toluene/ethyl acetate. Recrystallization from ethanol gave 16 g of pure 1-butyloxy-4-[4-(trans-4-pentylcyclohexyl)-l-butyl]benzene with m.p. (C-SB) 29° C. and cl.p. (SB --I) 43° C.
