4-Bromo-1-isothiocyanato-2-(trifluoromethoxy)benzene → HCID 16718095, compound

Participants

Reaction Steps

200 mg of 11-amino-2-[2-(dimethylamino)ethyl]-1H-dibenzo[de,h]isoquinoline-1,3(2H)-dione (obtained in example 3) (0.60 mmole) were dissolved in 15 ml of acetonitrile. 357 mg (2 molar equivalents) of 4-bromo-2-(trifluoromethoxy)phenyl isothiocyanate was added and the reaction mixture was maintained at room temperature for 16 hours. The solvent was then evaporated under reduced pressure and the residue was submitted to a flash chromatography (SiO2, CH2Cl2/MeOH 95/5). 356 mg of the desired product (formula shown hereinabove) were isolated as a red powder (yield=94%) which was characterized as follows:
