実験手順
To a solution of N1-Methyl-4-nitro-benzene-1,2-diamine (5 g, 30 mmol) in MeOH was added bromide isothiocyanate (4.4 g, 42 mmol) and the mixture was stirred at rt. After 16 h. 6N NaOH solution was added to the reaction mixture until Ph˜10 and MeOH was then removed in vacuo. H2O was added and the solid was filtered and dried to give the title compound as an off white solid (5.2 g, 90%). MS (ESI) m/z=193 [M+H]+.
