Procedure

A solution of tert-butyl-4-aminocyclohexylcarbamate (20.32 g, 95 mmol), bis(2-bromoethyl)ether (14.30 ml, 114 mmol) and triethylamine (33.0 ml, 237 mmol) in N,N-dimethylformamide (200 ml) was stirred for 16 hours at 70° C. The reaction mixture was cooled down to room temperature, concentrated and the product was extracted with ethyl acetate. The organic layer was washed with sodium carbonate solution (15% aq.), dried and concentrated. The product was used in next step without purification.
