YieldReaction ConditionsOperation in experiment
45% Sodium hydride (115 mg, 2.64 mmol) was suspended in N,N-dimethylformamide (20 mL), and known <strong>[91136-43-5]3-hydroxy-1-naphthaldehyde</strong> [Tetrahedron, 1999, Vol. 55, p.5821-5830] (250 mg, 1.45 mmol) was added at 0C. After stirring for 30 minutes, iodomethane (230 muL, 3.69 mmoL) was added, and the mixture was stirred at room temperature for one hour. A saturated ammonium chloride aqueous solution (20 mL) was added to the reaction solution, followed by extraction with diethyl ether (50 mL). The organic layer was washed with brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate = 10/1) to give the target compound (122 mg, yield: 45%) as a light yellow solid. 1H-NMR (CDCl3, 500MHz):delta ppm: 4.86 (3H, s), 7.38 (1H, m), 7.55-7.51 (2H, m), 7.64 (1H, m), 7.79 (1H, m), 9.90 (1H, m), 10.35 (1H, s).

YieldReaction ConditionsOperation in experiment
89% With pyridine; at 20℃; for 17h; Known <strong>[91136-43-5]3-hydroxy-1-naphthaldehyde</strong> [Tetrahedron, 1999, Vol. 55, p.5821-5830] (300 mg, 1.74 mmol) was dissolved in pyridine (3 mL). Dimethylcarbamoyl chloride (750 muL, 8.15 mmol) was added, and the mixture was stirred at room temperature for 17 hours. A saturated ammonium chloride aqueous solution (10 mL) was added to the reaction solution, followed by extraction with diethyl ether (40 mL). The organic layer was washed with brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (elution solvent: hexane/ethyl acetate = 4/1) to give the target compound (378 mg, yield: 89%) as a light yellow oil. 1H-NMR (CDCl3,400MHz):delta ppm: 3.06 (3H, s), 3.17 (3H, s), 7.55 (1H, m), 7.62(1H, m), 7.85-7.80 (3H, m), 9.15 (1H, d, J=8.6Hz), 10.34 (1H, s).

YieldReaction ConditionsOperation in experiment
~ 100% Sodium hydride (1.38 g, 31.6 mmol) was suspended in tetrahydrofuran (100 mL), and known <strong>[91136-43-5]3-hydroxy-1-naphthaldehyde</strong> [Tetrahedron, 1999, Vol. 55, p.5821-5830] (3.50 g, 20.3 mmol) was added at 0C. After stirring for 30 minutes, N-phenyl-bis(trifluoromethanesulfonimide) (7.30 g, 20.4 mmoL) was added, and the mixture was stirred at 0C for 1.5 hours. A saturated ammonium chloride aqueous solution (100 mL) was added to the reaction solution, followed by extraction with diethyl ether (200 mL). The organic layer was washed with brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (elution solvent: hexane/diethyl ether = 5/1) to give the target compound (6.50 g, yield: ~100%) as a light yellow solid. 1H-NMR (CDCl3, 400MHz):delta ppm: 7.69 (1H, m), 7.77 (1H, m), 7.87 (1H, brd, J=2.7Hz), 7.95 (1H, brd, J=8.2Hz), 8.00 (1H, brd, J=2.7Hz), 9.17 (1H, d, J=8.6Hz), 10.42 (1H, s).
