Procedure
3-[[2-[[Bis[bis(2-chloroethyl)amino]phosphinyl]oxy]ethyl]thio]-L-alanine methyl ester, 400 mg (0.8 mmol), was dissolved in 4 mL anhydrous tetrahydrofuran, and 550 μL (3.2 mmol) diisopropylethylamine added, followed by methanesulfonyl chloride, 181 mg (1.6 mmol). The reaction mixture was purged with argon and stirred overnight. After adding a further 275 μL (1.6 mmol) diisopropylethylamine, then tris(2-aminoethyl)amine-polystyrene resin, 480 mg (1.6 mmol), the mixture was agitated for 6 hours, then filtered and the filtrate evaporated to dryness under vacuum, giving N-(methanesulfonyl)-3-[[2-[[bis[bis(2-chloroethyl)amino]phosphinyl]oxy]ethyl]thio]-L-alanine methyl ester, 397 mg. Purity was verified with ELSD and identity verified with 1H and 31P NMR.
