4-Hydroxybenzaldehyde → 4-{[5-Amino-4-nitro-2-(trifluoromethyl)phenyl]oxy}benzaldehyde

Participants

Reaction Steps

A solution of 5-chloro-2-nitro-4-(trifluoromethyl)aniline (0.240 g, 1.00 mmol), potassium t-butoxide (0.135 g, 1.2 mmol), and 4-hydroxybenzaldehyde (0.147 g, 1.2 mmol) in dimethylformamide (5 mL) was heated to 80 degrees Centigrade for 6 hours and then cooled. Water was added and the organics extracted using ethyl acetate (2×50 mL). The combined organics were then washed once in brine and then dried (Na2SO4), filtered and concentrated. Chromatography on silica gel using a gradient of 30%-40% ethyl acetate/hexanes eluted the product to give 0.243 g of 4-{[5-amino-4-nitro-2-(trifluoromethyl)phenyl]oxy}benzaldehyde as an yellowish solid.
