To a solution of benzyl (2S)-2-hydroxy-4-methylvalerate (1.00 g) in tetrahydrofuran (20 ml) was added trichloromethyl chloroformate (0.55 ml) at room temperature. The solution was refluxed for 11 hours and the solvent was removed by evaporation at atmospheric pressure to give benzyl (2S)-2-chlorocarbonyloxy-4-methylvalerate (1.26 g) as an oil.
