A convenient and high-yield synthesis for N1-tritylethane-1,1,2,2-d4-1,2-diamine, a novel mono-protected ethylenediamine-C-d4, is reported. N1-tritylethane-1,1,2,2-d4-1,2-diamine was prepared in three steps from ethylene oxide-d4 in a combined yield in the range 68–76%. Also reported is a synthesis of ethylenediamine-C-d4 in two steps from 1,2-dibromoethane-d4 in a combined yield in the range 61–65%.
