Compounds of the general formula <FORM:1113807/C3/1> wherein R and R1 each represent hydrogen, alkyl, cycloalkyl, aryl, substituted aryl or phenylalkyl groups, or R and R1 together represent the ring members necessary to complete with the nitrogen atom a 5- or 6-membered heterocyclic ring, R11 represents an alkyl, aryl or substituted aryl radical, A represents a C2- 4 alkylene radical and n is an integer of from 1 to 40, may be prepared by reacting glycol ethers of the general formula <FORM:1113807/C3/2> with an amidophosphoric acid dihalide or a lower (up to C5) aliphatic ester thereof in a molar ratio of about 2:1 in the presence of a base such as pyridine.ALSO:Compounds of the general formula <FORM:1113807/C2/1> wherein R and R1 each represent hydrogen, alkyl, cycloalkyl, aryl, substituted aryl or phenylalkyl groups, or R and R1 together represent the ring members necessary to complete with the nitrogen atom a 5- or 6-membered heterocyclic ring, R11 represents an alkyl, aryl or substituted aryl radical, A represents a C2- 4 alkylene radical and n is an integer of from 1 to 40, may be prepared by reacting glycol ethers of the general formula <FORM:1113807/C2/2> with an amidophosphoric acid dihalide or a lower (up to C5) aliphatic ester thereof in a molar ratio of about 2:1 in the presence of a base such as pyridine. |
