To a solution of (5-methoxy-2-nitrophenyl)methanol (12.0 g, 65.6 mmol) in anhydrous THF (200 mL) and DMF (20 mL) was added imidazole (9.80 g, 144 mmol). Then TBSCl (11.8 g, 78.6 mmol) was added portionwise at 0° C. and the mixture was stirred at 30° C. for 2 hours. The mixture was quenched with ice-water (100 mL). An EtOAc workup was followed by removal of solvent in vacuo and purification by column chromatography (PE/EtOAc=10/1) to give the product (16.0 g, yield 84%) as a yellow oil.
