Procedure

350 mg (1.1 mmol) of 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylamine (Example compound 2, intermediate 1) were dissolved in 17.5 ml of dichloromethane and admixed with stirring with 230 mg (1.1 mmol) of 4-nitrophenyl chloroformate. After 4.5 hours, a further 0.1 equivalent (23 mg) of 4-nitrophenyl chloroformate was added and the solution was stirred overnight. For workup, the resulting precipitate was filtered off and washed with dichloromethane. The crude product obtained in this way could be reacted further without further purification.
