実験手順

To a solution of (R)-tert-butyl 3-(6-(5-(2-chloro-6-fluorophenyl)-1H-indol-3-yl)pyrazin-2-yloxy)piperidine-1-carboxylate (0.077 g, 0.147 mmol) in 1.5 mL DCM was added TFA (0.170 mL, 2.208 mmol). After 30 min, the reaction was concentrated in vacuo, taken up in DMSO, and purified by RPHPLC, 10-100% ACN/H2O with 0.1% TFA; product-containing fractions were combined and concentrated in vacuo to give (R)-5-(2-chloro-6-fluorophenyl)-3-(6-(piperidin-3-yloxy)pyrazin-2-yl)-1H-indole bis(2,2,2-trifluoroacetate) as an orange solid. MS (ESI, pos. ion) m/z: 423 (M+1).
