4-bromobenzylbromide (10.0 g, 40.0 mmol) was dissolved in triethylphosphite (8.4 mL, 48.0 mmol) under a nitrogen atmosphere, and the reaction solution was refluxed and stirred for 24 hours. The reaction solution was passed through a silica gel column by using hexane-ethylacetate 7:3 as an eluant. After the solvent was removed, the residue material was dried in vacuum to thereby obtain pale yellow oil (10.0 g, yield: 81%).
