YieldReaction ConditionsOperation in experiment
63% A solution of isopropylmagnesium chloride in tetrahydrofuran (2 M, 29.7 mL, 59.4 mmol) was added in a drop-wise manner to a 5 C. solution of C1 (12 g, 54.0 mmol) in tetrahydrofuran (60 mL), at a rate that maintained the internal temperature of the reaction mixture below 10 C. The reaction was allowed to proceed at 5 C., and aliquots were quenched into methanol and analyzed by HPLC to monitor the extent of Grignard formation; once full conversion was observed (?5 to 10 minutes), a solution of tert-butyl 2-oxopyrrolidine-1-carboxylate (11.0 g, 59.4 mmol) in tetrahydrofuran (60 mL) was added drop-wise, again at a rate which maintained the reaction temperature below 10 C. The reaction was monitored by HPLC, and when no additional conversion was observed (?1 hour), it was quenched via careful addition of aqueous acetic acid (10%, 60 mL) and ethyl acetate (100 mL). The organic layer was separated and washed with saturated aqueous sodium chloride solution (2*100 mL), dried over magnesium sulfate, filtered, and concentrated to a mass of 35 g. Heptane (40 mL) was added, to a total volume of approximately 80 mL, and approximately 20 mL of solvent was removed via heating at atmospheric pressure. The mixture was slowly cooled to 20 C., and the resulting thick slurry was allowed to stir overnight at 20 C., whereupon it was filtered. The filter cake was rinsed with cold heptane (0 C., 30 mL) to afford the product as a white solid.
