Reaction Steps

A mixture of 4-phenylbutyl chloride (8.0 g, 47.5 mmole) and triethylphosphite (15.0 ml, 72 mmole) was heated at reflux (bath temperature 185° C.) under argon for 41.5 hours. Distillation of the mixture gave pure diethyl (4-phenylbutyl)phosphonate (10.8 g, 84%) as a colorless liquid, b.p. 152°-154° C. (1.0 mmHg). TLC (EtOAc) single spot Rf =0.55.
