Reaction Steps

To a solution of 2-hydroxy-4-(methylthio)butanoic acid (50.74 g, 337.8 mmol, obtained by stirring Alimet over activated charcoal, filtering and concentrating in a rotovap) in dichloromethane (1 L) was added triethylamine (93 mL, 667.3 mmol) and the resulting mixture was cooled to 0° C. To the cooled mixture was added acetyl chloride (26 mL, 365.6 mmol) dropwise. The ice bath was removed and the reaction was allowed to warm to room temperature overnight. The reaction was washed with 1N HCl (2×300 mL), and brine (1×300 mL), dried over magnesium sulfate, filtered and evaporated to give an amber oil (59.82 g, 63.1%). m/z 193 (MH+).
