Anthraquinone-2,7-disulfonylchloride (10 g, 24.7 mmol)) was dissolved in 200 mL DCM. The solution was cooled to −50° C. To this solution was added 4-tert-butylcyclohexanamine (8.43 g, 54 mmol), followed by triethyl amine (8.6 ml, 61.7 mmol). The reaction mixture was stirred at room temperature for 4 hrs. Solvent was evaporated and the residue was treated with MeOH, filtered off, and dried to obtain 15 g (95%) of the product (1-36) as yellow powder.
