Versuchsvorschrift
540 g (3.0 mol) of ethyl(2-cyano-2-methylethyl)phosphinic acid (produced as in Example 6) are at 80° C. dissolved in 400 ml of toluene and admixed with 315 g (3.5 mol) of 1,4-butanediol and esterified at about 100° C. during 4 h in a distillation apparatus equipped with a water trap. After the esterification has ended, the toluene is separated off in vacuo to leave 643 g (92% of theory) of 4-hydroxybutyl ethyl(2-cyano-2-methylethyl)phosphinate as colorless oil.
