Procedure
To a mixture of cyclohexanol (10.9 g, 10.9 mmol), pyridine (8.62 g, 10.9 mmol) in dichloromethane was added 2-bromopropionyl chloride (18.53 g, 10.9 mmol) at 0° C. The resulting mixture was stirred at room temperature for 1 hr. The product was partitioned between hexane and 10% citric acid. The organic phase was separated, dried over MgSO4 and concentrated to yield 2-bromo-propionic acid cyclohexyl ester, which was used in the following reaction without further purification.
