Methanol → Methyl 1-(4-fluorophenyl)-2-oxopyrrolidine-3-carboxylate

Participants

Reaction Steps

To a solution of 1-(4-fluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (0.20 g, 0.90 mmol) in a mixture of Et2O (6 mL), MeOH (2 mL), and THF (2 mL) was added (diazomethyl)trimethylsilane (1.1 mL, 2.0 M) at 0° C. The resulting mixture was stirred for 30 minutes at room temperature, quenched with AcOH, and diluted with EtOAc. The organic layer was washed with water, NaHCO3 solution (2×), and brine, dried over MgSO4, and concentrated under reduced pressure to give the desired product (0.206 g, 98%). LRMS (ESI pos) m/e 238.0 (M+1).
