A synthesis of 2-amino-1-hydroxyethylene-1,1-bisphosphonic acid 3 has been developed from N-phthaloylglycine via dimethyl 2-(N-phthaloylamino)acetylphosphonate 1. The preparation of the N-methylated and N,N-dimethylated derivatives 4 and 5 has been achieved by the reaction of 3 with formic acid and formaldehyde. The synthesis of 1-amino-2-hydroxyethylene-1,1-bisphosphonic acid 9 (RR′H) and its N-methylated
