Participants

Reaction Steps

Add N,N-dimethylglycine (0.28 g, 2.68 mmol), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (0.47 g, 2.45 mmol), 1-hydroxybenzotriazole (0.33 g, 2.45 mmol), and methylene chloride (111 mL) to 6-bromo-[1,8]naphthyridin-2-ylamine (Reichardt, C. et al, Tetrahedron Lett. 1977, 2087; 0.50 g, 2.23 mmol). Stir the reaction at room temperature for 19 h, concentrate in vacuo and purify by flash column chromatography to provide the subtitled compound (0.41 g, 60%) as an orange solid. MS ESI+ m/e 309/311 (M+1). 1H NMR (DMSO-d6) δ 10.52 (m, 1H), 8.96 (m, 1H), 8.71 (m, 1H), 8.35 (m, 2H), 3.15 (s, 2H), 2.25 (s, 6H). TLC (SiO2): Rf0.3 (1:4 [80:18:2 chloroform/methanol/concentrated aqueous ammonium hydroxide]/dichloromethane).
