Reaction Conditions:
with sodium hydroxide in dimethyl sulfoxide;
Steps:
1 N-methyl-4-nitro-2-trifluoromethylaniline
Example 1 N-methyl-4-nitro-2-trifluoromethylaniline 1.91 g (10 mmol) of 3-nitrobenzotrifluoride and 1.76 g (20 mmol) of N,N'-dimethylurea are heated to 50° C. for 4 h with 1.2 g (30 mmol) of sodium hydroxide in the form of microbeads in 30 ml of DMSO, passing through an airstream. The mixture is then diluted with ethyl acetate and washed repeatedly by shaking with sainted soda solution. After drying the organic phase over sodium sulphate and taking off the solvent, 2.2 g (10 mmol, 100%) of N-methyl-4-nitro-2-trifluoromethylaniline are obtained as a 95% pure product of m.p. 99°-101° C. After recrystallization from ethanol the product has a m.p. of 111°-112° C.
