3-Dialkylamino (3) and 3-benzyloxycarbonylamino (6) esters are prepared by the Reformatsky reaction of 1-dialkylamino-(1) and 1-benzyloxycarbonylamino-(5) 1-(1-benzotriazolyl)alkanes with ethyl 2-bromoalkanoates. Compounds 1 and 5 are obtained by the condensation of benzotriazole, an aldehyde, and a secondary amine or benzyl carbamate. The procedure can be performed by as a one-pot reaction from benzotriazole.
