p-Fluoronitrobenzene → 1-Nitro-4-(2,2,2-trifluoro-1,1-dimethyl-ethoxy)-benzene

Participants

Reaction Steps

To a solution of 1-fluoro-4-nitro-benzene (2.82 g) and 1,1,1-trifluoro-2-methyl-propan-2-ol (2.3 ml) in DMF (90 ml) under an argon atmosphere was added under ice cooling NaH (0.914 g, 55% suspension in oil) and the mixture was stirred for 3 h at RT. It was then partitioned between diethyl ether and water, the layers were separated, dried over Na2SO4 and the solvent was evaporated off to give 1-nitro-4-(2,2,2-trifluoro-1,1-dimethyl-ethoxy)-benzene as a brown oil (4.9 g) that was used in the next step without further purification.
