tert-Butyl glycinate

6456-74-2

10 mmol of glycine, 4 g of molecular sieves, and 20 mL of methyl tert-butyl ether were added to a 50 mL round-bottomed flask fitted with a septum, and the mixture was cooled to 25 °C. 30 mmol of sulfuric acid was slowly added dropwise to the solution using a syringe. The reaction was maintained at 25 °C for the indicated time as shown in Table 5. Upon completion of the reaction, the reaction mixture was quenched by slowly pouring it into 25 mL of saturated aqueous sodium bicarbonate solution. The organic phase was separated and the aqueous phase was extracted twice with hexane. The organic phases were combined, washed with water and subsequently dried with anhydrous sodium sulfate. Finally, the solvent was removed by distillation to give tert-butyl glycinate.
