DOCUMENT TYPE: Patent CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 5, 29 (RO)2P(O)CH2NHCH2X.HCl (I; R = alkyl; X = CN, CONH2, CO2R) were hydrolyzed at 40-130° with 2-8 wt. equivs. aq. HCl to give 72-92% (HO)2P(O)CH2NHCH2CO2H (II) of 95-8% purity, useful as a herbicide. I were also prepd. in situ by treating H2CNCH2CN with ROH and PCl3 in 1:3-4:1-1.There are some commonly used reagents with their cas registry numbers 78285-76-4 and 109-82-0 in this article.2 molar ratio and <40° and hydrolyzed as above. Thus, 121 g (EtO)2P(O)CH2NHCH2CN.HCl were hydrolyzed in 400 mL refluxing aq. HCl to give 75% II of 98% purity. .
