Reaction Steps

Under nitrogen at 0°, a solution of 4-methyl-4-(2-acetoxyethyl)-2-azetidinone (0.014 mole) in 25 ml anhydrous methanol is treated with a solution of sodium methoxide (77 mg, 1.4 mmoles) in 5 ml anhydrous methanol. After stirring for 1 hour, the solution is neutralized with glacial acetic acid. Removal of the methanol in vacuo gives crude 4-methyl-4-(2-hydroxyethyl)-2-azetidinone as an oil. The product is purified by chromatography on silica gel eluting with 10% MeOH/CHCl3 to give the alcohol.
