Participants

Reaction Steps

A mixture of 1-(5-(6-((1R*,2S*)-5′-methoxy-2′-oxospiro[cyclopropane-1,3′-indoline]-2-yl)-1H-indazol-3-yl)pyridin-2-yl)piperidin-4-yl acetate (40 mg, 0.076 mmol) and aqueous NH4OH (0.03 mL, 14 M) in MeOH (3 mL) was stirred at rt for 17 h. The crude reaction mixture was concentrated under reduced pressure to dryness, and the resulting crude product was purified by preparative HPLC to give the title compound as a yellow solid and as the TFA salt (23 mg, 62%). 1H NMR (400 MHz, MeOD) δ 8.56 (dd, J=9.6, 2.0 Hz, 1H), 8.37 (d, J=1.6 Hz, 1H), 7.86 (d, J=8.5 Hz, 1H), 7.54 (s, 1H), 7.49 (d, J=9.6 Hz, 1H), 7.05 (d, J=8.5 Hz, 1H), 6.83 (d, J=8.4 Hz, 1H), 6.60 (dd, J=8.4, 2.4 Hz, 1H), 5.60 (d, J=2.3 Hz, 1H), 4.06-3.99 (m, 3H), 3.65-3.59 (m, 2H), 3.37-3.35 (m, 1H), 3.28 (s, 3H), 2.26-2.23 (m, 1H), 2.20-2.16 (m, 2H), 2.09-2.04 (m, 2H), 1.78-1.69 (m, 2H); MS ESI 482.3 [M+H]+, calcd for [C28H27N5O3+H]+ 482.21.
