実験手順
To a solution of salicylaldehyde (10 g, 82 mmol) in 50 mL of CH2 Cl2 is added 22 mL of a 1M ICl solution in CH2Cl2. The solution is stirred for 14 h. After this time, a saturated solution of sodium sulfite is added until the color is discharged. The solution is diluted with CH2Cl2. The layers are separated. The organic layer is washed with water. The organic layer is dried over MgSO4, filtered and concentrated. The resulting crude material is recrystallized from cyclohexane to give the title compound (7.2 g, 32 mmol) as white solid.
