Reaction Steps

A mixture of 4-chloro-2-fluoronitrobenzene (2.57 g, 14.6 mmols), tert-butyl[1-(3-hydroxyphenyl)-1-methylethyl]carbamate (3.21 g, 12.8 mmols), potassium carbonate (2.02 g, 14.6 mmols) and N,N-dimethylformamide (20 ml) was stirred at 100° C. for 2 hours. The reaction mixture was cooled, then poured into water, and extracted with ethyl acetate. The extract was washed with water and brine, and then dried with anhydrous magnesium sulfate, and the solvent was evaporated away. The residue was purified through silica gel column chromatography to give a crystal of tert-butyl[1-[3-(5-chloro-2-nitrophenoxy)phenyl]-1-methylethyl]carbamate (3.6 g, 69%).
