To a solution of 2,6-dichloro-3-nitrobenzyl alcohol (5.0 g) in N,N-dimethylformamide (25 ml) were added imidazole (1.69 g) and tert-butyldiphenylsilyl chloride (6.0 ml) at ambient temperature with stirring. After 8 hours, the mixture was diluted with water (25 ml) and was extracted with ethyl acetate twice. The organic layer was washed with water and brine, dried over magnesium sulfate.
