YieldReaction ConditionsOperation in experiment
96% 5-bromoindole-3-carbaldehyde 2 (10 mmol) was dissolved in acetonitrile and to this powdered NaOH (5 mmol) was added and stirred for 10 min. Methyl iodide (10 mmol) was added dropwise to the reaction mixture. After 3h of stirring at room temperature, the solvent was completely evaporated. It was extracted with ethyl acetate (3x20 ml) and dried over Na2SO4. The combined organic layer was concentrated in vacuo to give a light yellow color solid purified by recrystallization with diethyl ether.

91% With sodium hydride; In tetrahydrofuran; at 0℃; for 1.83333h; 5-Bromo-1-methyl-lH-indole-3-carbaldehyde; 5-Bromo-1H-indole-3-carbaldehyde (4.8 mmol, 1076 mg) was dissolved in 15 mL of THF and the solution was cooled to 0 C under N2-athmosphere. Sodium hydride (11.7 mmol, 280 mg) was added carefully in portions and iodomethane (8.1 mmol, 1150 mg) was added. The mixture was stirred at 0 C for 1 h. More iodomethane (8.1 mmol, 1150 mg) was added and the stirring continued for 50 min. The mixture was poured over ice and the resulting slurry was extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and evaporated. This gave 1037 mg (91 %) of the title product.

81% General procedure: To a suspension of NaH 60% in oil (2.25 equiv.) in dry DMF(0.8 mL/mmol) was added, at 0 C and under nitrogen atmosphere, a solution of indolecarboxaldehyde (1 equiv.) in dry DMF (2.5 mL/mmol). After stirring for 30 min at rt, alkyl halide (1.0e3.0 equiv.)was slowly added. After stirring overnight, the reaction wasquenched by addition of water and the product was extracted withdiethyl ether. The organic layer was dried over MgSO4, filtered offand concentrated under vacuum. The crude product was purifiedby column chromatography on silica gel.
General procedure: Compounds 7-9 were synthesized from the corresponding compounds 4-6. A solution of compounds 4-6 (60 mmol) in THF (30 mL) were added dropwise to a suspension of NaH (3.60 g, 60% dispersion in mineral oil, 150 mmol) in THF (30 mL) at 0 C. After stirring for 15 min, the heterogeneous mixture was treated with iodomethane (5.04 mL, 79.2 mmol) at room temperature for 1 h. Then the reaction mixture was cooled to 0 C, quenched with saturated NH4Cl (60 mL), and extracted with ether (3 * 50 mL). The organic layers were combined, washed with brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give 1-Methyl-1H-indole-3-carboxaldehyde (7-9), a light brown solid. The crude 7-9 were used in the next step without any further purification.
With sodium hydride; In tetrahydrofuran; at 0 - 20℃; for 24h; General procedure: The relevant indole-3-carboxaldehyde (2a-c, 10 mmol) in THF(25 mL) was added dropwise to a stirred solution of NaH (25 mmol)in THF (25 mL) at 0 C and CH3I (13.2 mmol) was added after 15 minstirring. The reaction mixturewas moved to room temperature andstirred for further 24 h. Then the solvent was removed in vacuumand the residue was extracted by ethyl acetate. The organic layerwas washed with brine, dried over anhydrous sodium sulfate,filtered and concentrated in vacuum. Recrystallization affordedcompound 3a-c with yields of 93.4-97.5%.

YieldReaction ConditionsOperation in experiment
With sodium ethanolate; In ethanol; at 20℃; General procedure: Various aldehydes (1.0 equiv) were added to stirred solutions of indolin-2-one, 5-chloroindolin-2-one or <strong>[5654-97-7]7-azaoxindole</strong> (1.0equiv) in absolute ethanol. After stirring at room temperature for 5 min NaOEt/EtOH (0.5 mL) was added and the mixture was then stirred at room temperature overnight. The solvent was then removed under vacuum. The residue was washed with saturated sodium chloride solution and then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and concentrated under vacuum. The solid part was purified by chromatography over silica gel using ethyl acetate/petroleum ether as the eluent to afford desired compounds 1a-1g, 2a, 3a.
