실험 절차
In a sealed container, 6-benzyl-5,6,7,8-tetrahydro-1,6-naphthyridine-2-carboxylic acid (1.00 g, 3.73 mmol) was dissolved in MeOH (40.0 mL) and HCl (3.29 mL, 14.9 mmol, 4.0 M in 1,4-dioxane). The resulting solution was heated at 80° C. for 13 h. The solvent and acid were completely evaporated to yield methyl 6-benzyl-5,6,7,8-tetrahydro-1,6-naphthyridine-2-carboxylate hydrochloride (1.25 g, 100%). LC-MS: (FA) ES+ 283; 1H NMR (Methanol-d4, 400 MHz) δ 8.08 (d, J=8.0 Hz, 1 H), 7.92 (d, J=8.3 Hz, 1 H), 7.63 (m, 2 H), 7.54 (m, 3 H), 4.88 (s, 2 H), 4.58 (s, 4 H), 3.99 (s, 3 H), 3.40 (s, 2 H).
