1-Fluoro-2-nitrobenzene → 5-Methyl-2-(2-nitro-phenylamino)-benzonitrile

참여 물질

반응 조건

반응 단계

Combine 1-fluoro-2-nitro-benzene (4.34 g, 30.79 mmol), 2-amino-5-methyl-benzonitrile (4.07 g, 30.79 mmol), lithium hydroxide monohydrate (2.58 g, 61.58 mmol) and DMSO (50.0 ml). Stir the mixture at 55° C. for 22 hours then cool it to ambient temperature. Pour the mixture onto ice chips and stir for 1 hour. Remove the resulting precipitate by vacuum filtration. Dry the precipitate under vacuum then purify it on silica gel using dichloromethane/hexanes (75:25) to give 4.45 g (57%) of an orange solid: mp 135–139°; mass spectrum (ion spray): m/z=254.0 (M+1).
