170161-27-0, General procedure: The dibromide was added to a solution of tri-tert-butyl 1,4,8,11-tetraazacyclotetradecane-1,4,8-tricarboxylate (39.1 mg, 78.0 mumol), KI (12.9 mg, 78.0 mumol) and K2CO3 (10.8 mg, 78.0 mumol) in CH3CN (2.50 mL) under N2 and stirred for 24 h at room temperature. The reaction mixture was concentrated under reduced pressure and extracted with EtOAc. The organic layer was washed with water and brine, dried with MgSO4 and concentrated in vacuo to obtain the corresponding tri-N-Boc-protected amine intermediate (130 mg). A solution of the intermediate was added to bis(pyridin-2-ylmethyl)amine (12.0 mg, 60.0 mumol), KI (9.96 mg, 60.0 mumol) and K2CO3 (8.30 mg, 60.0 mumol) in CH3CN (3.00 mL) under N2 and stirred at 80 C for 24 h. The reaction mixture was concentrated under reduced pressure and extracted with EtOAc. The organic layer was washed with water and brine, dried with MgSO4 and concentrated in vacuo to obtain the corresponding tri-N-Boc-protected amine intermediate. The intermediate was then dissolved in CHCl3 (2.50 mL) and treated with 95% aqueous TFA (2.50 mL) at 0 C for 6 h. The mixture was concentrated under reduced pressure and purified by preparative HPLC to obtain the desired compound 16.
