Diisopropylethylamine → 3-Fluoro-4-nitroanisole

Participants

Reaction Steps

A solution of 3-fluoro-4-nitrophenol (25 g, 0.159 mmol) in acetonitrile (500 mL) and methanol (500 mL) was treated with diisopropyl ethylamine (28 mL). The reaction mixture was cooled in an ice-bath and after 30 minutes, trimethylsilyldiazomethane was added dropwise. The mixture was stirred at room temperature for 18 hours then evaporated under vacuum to afford the product as an oil (29.4 g, 100%). MS (+ve ion electrospray) m/z 172 (MH+).
