207 g (1 mol) of butyl ethyl(3-aminopropyl)phosphinate (produced as in Example 15) and 242 g (1 mol) of triphenylborane are stirred in 400 ml of toluene at room temperature for 1 hour. Toluene is distilled off at reduced pressure to leave 449 g (100% of theory) of butyl ethyl(3-aminopropyl)phosphinate as triphenylborane adduct.
