In this Example, 0.45 g of the 4-bromobutyrophenone (purity: 94%, 1.86 mmol) obtained in Example 1 was dissolved in 2.2 g of methanol, and 0.14 g of 5% Pd-C (50% wet) was added, followed by stirring the mixture in a hydrogen atmosphere at 20° C. for four hours. The catalyst was filtered off and the solvent was removed by distillation under reduced pressure to give 1-bromo-4-phenylbutane in a 98.2% yield from 4-bromobutyrophenone.
