The general procedure for the synthesis of 3-chloro-4-hydroxybenzaldehyde from 4-hydroxybenzaldehyde was as follows: N-chlorosuccinimide (1.1 g, 8.18 mmol) was added to a solution of 4-hydroxybenzaldehyde (1.0 g, 8.18 mmol) dissolved in 10 ml of chloroform. The reaction mixture was heated and stirred at 50°C for 15 hours. After completion of the reaction, it was cooled to room temperature and concentrated under reduced pressure to remove the solvent. The residue was dissolved in 25 ml of ethyl acetate, washed sequentially with water and saturated saline, and the organic phase was dried with anhydrous sodium sulfate. After filtration, the crude product was obtained by concentration under reduced pressure. The crude product was purified by silica gel column chromatography using 12% ethyl acetate in hexane solution as eluent to give 1.1 g (86% yield) of 3-chloro-4-hydroxybenzaldehyde.1H-NMR (400 MHz, CDCl3) δ (ppm): 9.840 (s, 1H), 7.898-7.894 (d, 1H, J = 1.6 Hz), 7.749- 7.724 (dd, 1H, J = 8.4Hz), 7.164-7.143 (d, 1H, J = 8.4Hz), 6.288 (s, 1H).
