Procedure
A solution of (1R*,2S*)-5′-methoxy-2-(3-(4-(piperazin-1-yl)phenyl)-1H-indazol-6-yl)spiro[cyclopropane-1,3′-indolin]-2′-one 2,2,2-trifluoroacetate (30 mg, 0.052 mmol) in 1,2-dichloroethane (0.5 mL), MeOH (0.1 mL) was treated with acetone (80 uL, 1.04 mmol) and NaBH(OAc)3 (17 mg, 0.078 mmol) and the reaction was heated to 40° C. for 18 h. The solvent was removed and the residue purified by column chromatography (silica gel, CH2Cl2/MeOH/7N NH3 in MeOH, 96:3:1) which gave an impure solid that was sonicated in Et2O. The solvent was decanted off and the solid dried to give the title product as an off-white powder (12 mg, 46%); 1H NMR (400 MHz, DMSO-d6) δ 12.99 (s, 1H), 10.44 (s, 1H), 7.91 (d, J=8.8 Hz, 1H), 7.81 (d, J=8.4 Hz, 2H), 7.47 (s, 1H), 7.06-6.99 (m, 3H), 6.74 (d, J=8.5 Hz, 1H), 6.57 (d, J=7.5 Hz, 1H), 5.69 (s, 1H), 3.29 (s, 3H), 3.25-3.15 (m, 4H), 2.67 (m, 2H), 2.65-2.55 (m, 4H), 2.35-2.32 (m, 1H), 2.22-1.98 (m, 1H), 1.01 (d, J=5.6 Hz, 6H); MS ESI [M+H]+ 508.3, calcd for [C31H33N5O2+H]+ 508.27.
