1-(4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperidin-4-yl acetate → 1-(4-(6-((1R*,2S*)-5'-methoxy-2'-oxospiro[cyclopropane-1,3'-indoline]-2-yl)-1H-indazol-3-yl)phenyl)piperidin-4-yl acetate

Participants

Reaction Steps

The title compound was synthesized according to the method described for example A45 except reacting a (1R*,2S*)-2-(3-iodo-1H-indazol-6-yl)-5′-methoxyspiro[cyclopropane-1,3′-indolin]-2′-one (76 mg, 0.18 mmol) with 1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperidin-4-yl acetate (67 mg, 0.19 mmol). Crude product was purified by flash chromatography using EtOAc/Hexanes (2:3 to 1:0) to give the title compound as a yellow solid (38 mg, 41%). MS ESI 523.3 [M+H]+, calcd for [C31H30N4O4+H]+ 523.23.
