실험 절차

A solution of 2.0 M methylamine in MeOH (75 mL) was added to 5-bromo-2-(methoxycarbonylmethyl)aminopyridine (2.9 g, 12 mmole). The reaction was stirred for 24 h then was concentrated to dryness. The residue was triturated with 10% petroleum ether/Et2O (100 mL), then was collected and dried under vacuum to give the title compound (2.96 g, 100%) as an off-white solid: MS (ES) m/e 244.2 (M+H)+.
