Reaction Steps
Racemic tert-butylglycine (502 mg, 3.83 mmol) was dissolved in water (10 mL) containing NaOH (153 mg, 3.83 mmol). This solution was cooled to 5° C. and treated with o-toluoyl chloride (0.501 mL, 3.83 mmol) followed by additional NaOH (153 mg, 3.83 mmol). The mixture was warmed to ambient temperature, stirred for 1.5 hours, recooled to 5° C., and treated with 1M HCl (pH 3). The thick precipitate that formed was collected by filtration and washed with cold water to provide 550 mg of the desired product as a white solid.
