Participants

Reaction Steps

A solution of (E)-benzyl 2-(4-((1-oxo-1,3-dihydroisobenzofuran-4-ylimino)methyl)phenyl)pyrrolidine-1-carboxylate (0.5 g, 1.14 mmol) and 4-fluoro benzaldehyde (0.284 g, 2.28 mmol) in dry ethyl propionate (5 mL) was added EtONa (0.155 g, 2.28 mmol) in EtOH (6 mL), and the mixture was stirred at room temperature until the starting material was disappeared as monitored by TLC. Then the reaction mixture was quenched with 0.5 mL of water, the resulting mixture was concentrated in vacuo, and the residue was purified by column chromatography to give the title compound (130 mg, yield 20%) as a yellow solid. LC-MS (ESI) m/z: 592 (M+1)+.
