Reaction Steps

A mixture of 84.5 g. (0.5 m.) of 2-nitro-4-methoxyphenol (part A), 338 g. of K2CO3 and 1200 ml. of dimethylformamide was heated on a steam bath for 60 minutes, then there was added dropwise, 76.7 ml. (108.98 g. 1.0 m.) of ethyl bromide. The mixture was heated and stirred overnight, then poured into 5 liters of ice water. The product was collected by filtration, washed with H2O and air-dried to give 92 g. m.p. 37°-39°C.
