Reaction Steps

1-Nitro-4-hydroxy-2-trifluromethylbenzene (5.0 g, 14 mmol) and cyclopropylcarbinol (1.75 g, 24 mmol) were dissolved in THF (20 mL) under nitrogen. Triphenylphosphine (9.5 g, 36 mmol) was added and diethyl azodicarboxylate (5.7 mL, 36 mmol) dissolved in THF (10 mL) was added over 30 minutes. The reaction mixture was stirred at 20° C. for 16 hours and then concentrated in vacuo. The residue was dissolved in ethyl acetate (25 mL) and heptane (40 mL). The mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by flash chromatography (350 g silica) using heptane and ethyl acetate (9:1) as eluent to give 1.4 g of 4-cyclopropylmethoxy-1-nitro-2-trifluoromethylbenzene.
