Dry ethanol (40 mL) was cooled on an ice bath and thionyl chloride (4 mL) was added dropwise maintaining the temperature below 5° C. To this cold solution was added (RS)-isoserine (2.5 g, 23.79 mmol) and stirring was continued until a homogeneous solution was obtained. The ice bath was removed and stirring was continued for 17 hours at room temperature. The solution was concentrated in vacuo to afford 4.0 g (100%) of (RS)-isoserine ethyl ester hydrochloride as an oil.
