실험 절차

To a solution of 2-(6-Butoxy-1,4-dioxo-1,4-dihydro-2-naphthalenyl)-2-methylpropanal (compound 5 prepared in step (I) above) (53 mg, 0.18 mmol) in MeOH (5 mL) and water (0.5 mL), 50% NH2OH in water solution (17 μL, 0.28 mmol) was added. The mixture was stirred 3 h at room temp and the solvent was evaporated. The crude product was fairly pure and was taken into the next step without further purification. Yield: 52 mg (92%). 1H NMR (400 MHz, CDCl3) δ 0.99 (tr., 3H), 1.38 (s, 3H), 1.52 (s, 3 H), 1.55 (m, 2 H), 1.84 (quint., 2H), 4.13 (tr., 2H), 5.31 (s, 1 H), 6.43 (s, 1H), 7.24 (d, 1 H), 7.73 (d, 1 H), 9.07 (d, 1 H).
