Reaction Steps
To a solution (300 mL) of methyl 4-chloro-3-oxobutanoate (27.1 g) in tetrahydrofuran was added morpholine (34.5 g) under ice-cooling. The ice bath was removed, and the reaction mixture was stirred at room temperature for 2 hr. The solvent was evaporated under reduced pressure, 1N hydrochloric acid (100 mL) was added, and the mixture was extracted with diethyl ether. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:10, volume ratio) to give the title object compound (12.8 g, 35%) as a yellow oil.
