    • In principle, a three-step route comprising selective N-protection of tris(hydroxymethyl)aminomethane followed by O-alkylation and deprotection could also lead to the desired product, but the present route is preferred because only two steps are necessary and there is only one reactive group present under the conditions of each step.
