Procedure

Reaction of tetrakis(hydroxymethyl)phosphonium benzenesulfonate (15.61 g, 0.05 mol) with 1,3-dimethylurea (17.62 g, 0.2 mol) in toluene (200 ml), following Example 1, gave 21.91 g (73.9%) of tetrakis(1,3-dimethylureidomethyl)phosphonium benzenesulfonate (I, R=R'=CH3, R"=H, X=SO3C6H5) as a white, crystalline solid, mp 103°-105° C. after three recrystallizations from acetonitrile (3 ml/g). The analytical sample, dried under vacuum for 4 hr at 56° C. (acetone), analyzed as a hydrate.
