Abstract
Abstract A method for synthesizing compounds of formula: ##STR1## in which R' and R" (I) are the same or different monovalent branched or unbranched alkyl groups of from 1 to 18 carbon atoms, optionally substituted by from 1 to 2 hydroxyl groups, the sum of the carbon atoms in R' and R" being at least three; or (II) form a 5, 6, or seven membered ring when taken together with N; or (III) form the N-Morpholino group when taken together with N and Oxygen, wherein Z represents either X or --N R'R", wherein X is a halogen of atomic weight above 30, and wherein n represents an integer of from 2 to 20.
