98% Example 1 Preparation of P001 Indole-7 carboxyldehyde (I-1). Ethyl Indole-7 m carboxylate was prepared according to literature procedure {Batcho B. and Leimgruber, K., Org. Syn. Vol IIV, page 34-40). To a solution of methyl 7-indolecarboxylate (13 g, 74.2 mmol) in 250 ml of anhydrous THF was added LiAlH4 (10.9 g, 0.288 mol) in portions, and reaction mixture was heated to reflux for 2 h. After cooling to room temperature, the excess hydride was quenched by addition of water (12 mL), 15percent NaOH (12 mL) and water (26 mL). The solids were removed by filtration through a pad of Celite and filtrate was evaporated in vacuo to yield (1H-indol-7-yl)-methanol (10.7 g, 98percent). 1H-NMR (CDCl3).

To a solution of the alcohol, (IH- indol-7-yl)-methanol (8.0 g, 54.3 mmol) in 400 mL of methylene chloride was added activated manganese (IV) oxide (85percent, 41.0 g, 0.40 mol), and stirred at ambient temperature for 72h. After additional of 200 mL of methylene chloride and 400 mL of methanol to the reaction mixture, the whole mixture was filtered through a pad of silica gel to remove solid materials. The filtrate was concentrated to afford a crude product, which was purified by a column chromatography on silica gel to yield lH-indole-7-carbaldehyde, K-44 (6.55 g, 83percent).
With acetic acid; In tetrahydrofuran; ethyl acetate n-hexane; iii) 7-Indole methanol Solid lithium aluminum hydride (1.0 g) was added in portions over 1 hour to a stirred solution of methyl 7-indolecarboxylate (6.7 g) in tetrahydrofuran (100 ml). The mixture was stirred for a further 2 hours then excess lithium aluminium hydride was destroyed by addition of acetic acid, the mixture was diluted with aqueous sodium hydroxide and extracted with ethyl acetate. The extract was dried and evaporated and the residue was chromatographed on silica in ethyl acetate-hexane (1:9 to 1:2) to give the product.

YieldReaction ConditionsOperation in experiment
(Intermediate Example 33) 1-Methyl-1H-indole-7-carboxylic acid Methyl 1H-indole-7-carboxylate (546 mg) was dissolved in N,N-dimethylformamide (8 ml) and cooler to 0C. Sodium hydride (370 mg) was added thereto and stirred as such for 30 minutes. Methyl iodide (0.38 ml) was added slowly dropwise thereto, and the mixture was warmed to room temperature and stirred for 2 hours. The mixture was diluted with ethyl acetate, and the organic phase was washed with 2 N hydrochloric acid, a saturated sodium bicarbonate solution and a saturated saline solution. The resulting product was dried over sodium sulfate anhydrous and then concentrated under reduced pressure. 1,4-Dioxane (14 ml) and 1 N sodium hydroxide solution (14 ml) were added to the above compound and stirred for 17 hours at 40C. The mixture was acidified by 2 N hydrochloric acid and extracted with chloroform. The extract was dried over sodium sulfate anhydrous and then concentrated under reduced pressure. Precipitates were collected by filtration, washed with n-hexane and dried under reduced pressure to give the title compound (296 mg, Y.: 55%). 1H NMR; (DMSO-d6) delta (ppm): 3.8 (1H, s), 6.5 (1H, d), 7.1 (1H, t), 7.4 (1H, d), 7.5 (1H, dd), 7. 7 (1H, dd).
