Reaction Steps

A mixture of ethyl 5-phenyl-3-methylpentanoate (0.30 g, 1.36 mmol), a 1N-aqueous sodium hydroxide solution (3 ml), methanol (3 ml) and tetrahydrofuran (3 ml) was stirred at room temperature for 5 hours. The reaction mixture was adjusted to pH 1 with a 1N-aqueous hydrochloric acid solution and extracted with ethyl acetate. The extract solution was washed with water and a saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 0.24 g of 5-phenyl-3-methylpentanoic acid.
