A method for the synthesis of a series of water-soluble heptamethine indocyanine dyes containing a phosphonate group in the substituent bonded to the quaternary nitrogen atom of the indolenine moiety has been developed.
Diethyl alkylphosphonates are efficiently and rapidly prepared in good yields (75-99%) from trialkylphosphates and alkyl halides under short microwaves irradiations.
