The procedure of Example 1 is repeated using 13.3 g (50 mmol) of 3,9-dichloro-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, 27.1 g (100 mmol) of octadecylamine and 15 mL (110 mmol) of triethylamine in 350 mL of toluene to give a crude reaction residue. The residue is purified by recrystallization from a mixture of toluene and acetonitrile to give 33 g (90% yield) of the title compound as an off-white solid melting at 67°-70° C.
