Procedure

To a solution of tert-butyl {2-[({[6-chloro-2,4,8,22-tetraazatetracyclo[14.3.1.1(3,7).1(9,13)]docosa-1(20),3(22),4,6,9(21),10,12,16,18-nonaen-12-yl]amino}carbonyl)amino]ethyl}carbamate (326 mg, 0.622 mmol) in DCM (12 mL) was added 4.0 M of hydrogen chloride in 1,4-dioxane (0.544 mL, 2.18 mmol). After stirring overnight, the reaction solution was diluted with ether. The resulting precipitate was filtered and dried under vacuum to give the desired product (245 mg, 79%). LCMS calculated for C21H23ClN7O (M+H)+: m/z=424.2.
