Reaction Steps
Diisopropyl amine (0.12 moles) was added to a flask and diluted with 40 mL of toluene. The resultant was cooled to −78° C. under nitrogen, and then a hexane solution of n-butyl lithium (0.11 moles) was added thereto, followed by stirring at −78° C. for 1 hour. To this, 2-morpholinopropionic acid ethyl ester (0.105 moles) was added and the resultant was further stirred for 1 hour, and iodomethane (0.21 moles) was added thereto and after the temperature was restored to room temperature, the mixture was stirred for 1 hour. The reaction mixture was quenched with ice water, extracted with ethyl acetate and washed with a saturated sodium chloride aqueous solution, and then the organic layer was dried over magnesium sulphate. The solvent was evaporated, and the residue was purified by column chromatography (hexane/ethyl acetate=4/1) to obtain α-morpholino isobutyric acid ethyl ester (0.55 moles).
