In diethyl ether at 0 - 20℃; for 2h; Inert atmosphere; 3.1.3. General procedure for the synthesis of compounds 29 and 32-34 General procedure: To a solution of appropriate intermediates 10-12 (1 mmol) in diethyl ether (5 mL) the oxalyl chloride (0.173 mL, 2 mmol) was added slowly at 0 °C under nitrogen atmosphere. The reaction mixture was stirred at room temperature for 2 h. A saturated aqueous NaHCO3 solution (5 mL) was added to quench the reaction and the mixture was extracted with EtOAc (3 x 10 mL). The combined extracts were dried with dry Na2SO4 and concentrated in vacuo. A mixture of crude compounds (20-22) (1 mmol) and N,N,N,N-tetramethyl- O-(1H-benzotriazol-1-yl)uronium hexafluorophosphate (HBTU) (379 mg, 1 mmol) in dimethylformamide (2 mL) was stirred for 30 min at room temperature. Successively, 4-benzylpiperidine (0.175 mL, 1 mmol) or 4-fluorobenzylpiperidine (193.3 mg, 1 mmol) and TEA (0.139 mL, 1 mmol) were added, the reaction mixture was stirred for 2 h at room temperature. Then the reaction mixture was quenched with H2O (10 mL) and extracted with EtOAc (3 x x10 mL). The combined extracts were dried with dry Na2SO4 and concentrated in vacuo. The crude compounds were purified by flash chromatography (FC) (DCM/MeOH 96:4) and recrystallized by treatment with Et2O to give the desired final products 29, 32-34.

Stage #1: carbon dioxide; tert-butyl N-(1H-indol-6-yl)carbamate With lithium tert-butoxide In N,N-dimethyl-formamide at 100℃; for 24h; Stage #2: methanol With thionyl chloride at 0℃; for 2h; Reflux; Stage #3: With palladium 10% on activated carbon; hydrogen In methanol for 2h; Inert atmosphere; 15 Methyl 6-((tert-butoxycarbonyl)amino)indoline-3-carboxylate tert-Butyl (1H-indol-6-yl)carbamate (1 equiv.) is dissolved in dry N,N- dimethylformamide. Lithium tert-butoxide (5 equiv.) is added. Carbon dioxide is bubbled through the solution which is then heated to 100 °C. After 24 h, the reaction is cooled to room temperature and quenched with saturated ammonium chloride aqueous solution. The mixture is diluted with ethyl acetate and the organic layer is separated. The aqueous layer is extracted with ethyl acetate (3 x) and the combined organic layers are washed with brine and dried over sodium sulfate before concentrating. The resulting carboxylic acid is then dissolved in methanol and cooled to 0 °C. Thionyl chloride (1 equiv.) is added slowly. The reaction mixture is heated to reflux for 2 hours. It is then cooled to room temperature and diluted with ice water. The mixture is extracted with ethyl acetate (3 x) and the combined organic layers are washed with saturated sodium bicarbonate solution and then brine before drying with sodium sulfate. The mixture is concentrated and purified on silica to provide the desired methyl ester. The methyl ester is then dissolved in methanol. Palladium on carbon (10% by wt) is then added and the solution is degassed 3 times by replacing the air with nitrogen and finally the nitrogen with hydrogen. The reaction mixture was further stirred under hydrogen atmosphere for 2 h. The hydrogen gas was then purged and the mixture was filtered through a pad of celite and washed with methanol. The solvent was removed under vacuum and the resulting material was purified on silica to provide methyl 6-((tert-butoxycarbonyl)amino)indoline-3-carboxylate.

77% With tetrabutylammomium bromide; sodium hydroxide In dichloromethane at -20℃; for 3h; Inert atmosphere; 126.b Step b. To a suspension of NaOH (1.21 g, 30 mmol) in dry DCM (7 ml_) at -20°C under N2 atmosphere was added tert-butyl 1 H-indol-6-ylcarbamate (700 mg, 3.01 mmol), TBAB (48 mg, 0.15 mmol) and p-toluenesulfonyl chloride (5.75 g, 30 mmol) sequentially. The resulting mixture was stirred under N2 atmosphere at -20°C for 3 h. Then the mixture was slowly warmed to rt and stirred for 9 h. Upon completion, the mixture was diluted with water (100 ml_), extracted with EtOAc (100 ml_ x 2). The combined organic layers were washed with brine (80 ml_), dried and evaporated. The residue was purified by column chromatography (10% EtOAc in PE) to give tert-butyl (1-tosyl-1H-indol-6-yl)carbamate (0.9 g, 77% yield) as a white solid. m/z ES+ [M+Na]+ 409.1
