Synthesis

At -10 °C, 4 L of anhydrous tetrahydrofuran (THF) was added to a 30 L reaction kettle. After initiating stirring, zinc chloride (118 g, 0.86 mol) and lithium chloride (402 g, 9.5 mol) were added sequentially to the reactor. After half an hour, an ether solution (6.4 L, 19.2 mol) of methylmagnesium bromide (3 mol/L) was added slowly and dropwise to the reaction mixture. Stirring was continued for half an hour. Subsequently, a THF solution of 1-tert-butoxycarbonyl-3-pyrrolidone (1600 g, 8.6 mol) was added slowly dropwise. The progress of the reaction was monitored by high performance liquid chromatography (HPLC) and after confirming the completion of the reaction, saturated ammonium chloride (NH4Cl) solution was added slowly and dropwise to quench the reaction. The reaction mixture was extracted with ethyl acetate and the organic phase was washed with saturated aqueous sodium chloride (NaCl) solution and dried with anhydrous sodium sulfate. Finally, the solvent was removed by evaporation to afford the target product tert-butyl 3-hydroxy-3-methylpyrrolidine-1-carboxylate as a light yellow solid (1450 g) in 83.8% yield.
