반응 단계
To a solution of 3,5-diisopropyl-4-hydroxybenzaldehyde (0.95 g, 4.6 mmol) and 2-nitrophenyl acetic acid (1.1 g, 6.2 mmol) in xylene (10 ml) was added piperidine (0.05 ml) and the mixture was heated under reflux for 8 hrs while removing water producing with the progress of reaction. After distilling off the solvent followed by purification of the residue by a silica gel column chromatography, recrystallization from hexane gave 2,6-diisopropyl-4-(2-nitrostyryl)phenol (1.3 g, 87%) as crystals.
