Procedure: On an ice-water bath, to the solution of 1,7-diaminoheptane (1.433 g, 11 mmol) in CH2Cl2/MeOH (125 mL/125 mL) was added the solution of CbzCl (1.71 g, 10 mmol) in CH2Cl2 (250 mL) dropwise within 12 h while keeping the temperature below 5° C. The mixture was allowed to stir at the same temperature for another half of an hour before concentrated under reduced pressure to remove most of the MeOH. Water (150 mL) was then added, and the aqueous layer was adjusted to pH=2 using 6 N HCl. The layers were separated. The aqueous layer was washed with DCM (50 mL×3), then adjusted to pH=12 with 10 N NaOH and extracted with DCM (50 mL×3).
