Reaction Steps

Methyl 3-oxopentanoate (1 g, 7.68 mmol) was dissolved in chloroform (30 mL). Bromine (0.4 mL, 7.80 mmol) was added under ice-cooling and the mixture was stirred for 40 minutes. The reaction solution was washed with saturated aqueous sodium bicarbonate solution, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resulting compound was used for the next reaction without purification.
