Reaktionsschritte

Combine 1-fluoro-2-nitro-benzene (5.34 g, 37.83 mmol), 2-amino-4-methyl-benzonitrile (5.00 g, 37.83 mmol), lithium hydroxide monohydrate (3.17 g, 75.66 mmol) and DMSO (70.0 ml) and stir at 55° C. Afer 16 hours; cool to ambient temperature, pour the mixture onto ice chips and stir. After 1 hour, remove the resulting yellow precipitate by vacuum filtration. Dry the precipitate under vacuum, recrystallize in ethanol to give 5.15 g (54%) of fine, amber colored needles: mp 162-164° C.; mass spectrum (ion spray): m/z 254.0 (M+1).
