실험 절차

To a slurry of tert-butyl 1-(6-(5-(2-chloro-6-fluorophenyl)-1-tosyl-1H-indol-3-yl)pyrazin-2-yl)piperidin-4-ylcarbamate (0.186 g, 0.275 mmol) in 2 mL MeOH was added sodium methanolate 25 wt % in MeOH (0.126 mL, 0.550 mmol). 2 mL THF was added. The cloudy mixture was sealed and stirred rapidly. After 1 h, additional sodium methanolate 25 wt % in MeOH (0.126 mL, 0.550 mmol) was added. The reaction became a clear, orange solution. After 2 h, the reaction was concentrated under a stream of N2, and the solid was partitioned between saturated aqueous NH4Cl and DCM. 1 mL 1N HCl was added to acidify the aqueous layer. The aqueous layer was extracted with DCM 3 times, and the combined organics were dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The material was treated with DCM/MeOH and adsorbed onto 1.5 g silica gel, dried, and purified by silica gel chromatography (40 g column) using 20-80% EtOAc/hexane. The product-containing fractions were concentrated to afford tert-butyl 1-(6-(5-(2-chloro-6-fluorophenyl)-1H-indol-3-yl)pyrazin-2-yl)piperidin-4-ylcarbamate (0.104 g, 0.199 mmol, 72.4% yield) as a orange solid. MS (ESI, pos. ion) m/z: 522 (M+1).
