실험 절차

Mono-methyl isophthalate (1 g, 5.55 mmol), amino acetaldehyde dimethyl acetal (569 μL, 5.28 mmol) and EDCI (1.52 g, 7.92 mmol) were dissolved in 55 mL DCM, followed by the addition of DIPEA (1.84 mL, 10.56 mmol). The reaction was allowed to stir at room temperature for 2 hours. It was then taken up in 50 mL of DCM, washed with saturated NaHCO3 solution (100 mL), and brine (100 mL). The organic layer was dried over MgSO4, filtered and concentrated to afford the crude product (1.48 g) as a clear oil which was used in the next step without further purification.
