Dichloromethane → Methyl 6-(benzyl(2-ethoxy-2-oxoethyl)amino)-5-nitronicotinate

Participants

Reaction Steps

Methyl 6-chloro-5-nitronicotinate (2.0 g, 9.23 mmol) was added to methyl 2-(benzylamino)acetate (6.0 g, 31.05 mmol) neat while stirring at room temperature. The viscous yellow reaction was heated to 90° C. for one h and then allowed to cool back to room temperature. The reaction was diluted with dichloromethane (20 mL) and purified via column chromatography (220 g SiO2, 20-30% gradient, ethyl acetate in hexanes) to yield the title compound (3.10 g, 90% yield) as a yellow oil. [M+H] calc'd for C, 18; H, 19; N, 3O, 6, 374; found, 374.
