Procedure

The Suzuki coupling was executed according to the method in Example A45, except substituting tert-butyl 2-(3-iodo-1H-indazol-6-yl)-2′-oxospiro[cyclopropane-1,3′-indoline]-5′-ylcarbamate (70 mg, 0.136 mmol), 1-methyl-4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperazine (57 mg, 0.190 mmol). The resulting product was was dissolved into CH2Cl2 (1.0 mL) and TFA (50 uL) was added. After 1 h the reaction was complete, the solvent was removed and the residue purified by prep-HPLC to give a white powder (3.2 mg, 15%); 1H NMR (400 MHz, CD3OD) δ 7.94 (d, J=8.6 Hz, 1H), 7.87 (d, J=8.4 Hz, 2H), 7.53 (s, 1H), 7.18 (d, J=8.8 Hz, 2H), 7.05-7.02 (m, 3H), 6.04 (s, 1H), 4.01-3.97 (bs, 2H), 3.75-3.65 (bs, 2H), 3.46 (t, J=8.4 Hz, 1H), 3.32-3.28 (bs, 2H), 3.18-3.08 (bs, 2H), 3.00 (s, 3H), 2.35-2.31 (m, 1H), 2.29-2.25 (m, 1H); MS ESI [M+H]+ 465.1, calcd for [C28H28N6O+H]+ 465.24.
