Procedure

The 2,6-bis(chloromethyl)-4-nitrophenol (8 g) and p-chlorophenol (8.7 g) were dissolved in nitrobenzene (125 ml) at 25°. After cooling to 10° ZnCl2 (28 g) was added over 1 hr. The stirred mixture was held at room temperature for 30 hrs and poured into 200 mls of water. The organic layer was washed with water and the nitrobenzene removed by vacuum distillation. Column chromatography gave 1.5 g of 2,6-bis(5-chloro-2-hydroxybenzyl)-4-nitrophenol (mp 220°).
