Cyclohexene → HCID 22393276, compound

Participants

Reaction Steps

A mixture of 4-{N-[3-(imidazol-1-yl)propyl]carbamoyl}nitrobenzene (Method 41; 2.0 g, 7.30 mmol), 10% palladium on carbon (100 mg) cyclohexene (40 ml) and ethanol (80 ml) was heated under reflux under an atmosphere of nitrogen for 4 hours. Two further portions of cyclohexene (40 ml) were added and heating was continued for 1 hour after each addition. The mixture was left to cool and the catalyst was removed by filtration. The filtrate was concentrated by evaporation and the residue was recrystallized from a mixture of ethanol and ether to give the product (1.2 g, 67%). NMR: 1.9-2.0 (m, 2H), 3.1-3.2 (m, 2H), 4.0 (t, 2H), 5.6 (br s 2H), 6.55 (d, 2H), 6.85 (s, 1H), 7.2 (s, 1H), 7.55 (d, 2H), 7.65 (s, 1H), 8.0 (br t, H).
