実験手順

A glass microwave reaction vessel was charged with (R)-tert-butyl 3-(6-(5-(2,6-difluorophenyl)-1H-indol-3-yl)pyrazin-2-yloxy)piperidine-1-carboxylate (1.91 g, 3.77 mmol) in DCM (10 mL)/TFA (4 mL). The reaction mixture was stirred and heated in a Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Uppsala, Sweden) at 80° C. for 15 min, and then the solvent was removed. The residue was purified with RP-HPLC to give (R)-5-(2,6-difluorophenyl)-3-(6-(piperidin-3-yloxy)pyrazin-2-yl)-1H-indole.
