30 g of 2-chloro-5-nitrobenzaldehyde was dissolved in 500 ml of methanol and cooled to 0° C. A solution of 10 g of sodium borohydride in 100 ml of water was then added dropwise over 90 minutes while maintaining the temperature below 10° C. The resultant reaction mixture was then stirred for one hour, then acidified with 2N HCl and left stirring overnight. The solids were then, washed with water and dried, to produce 27 g of 2-chloro-5-nitrobenzyl alcohol as a white solid.
