Versuchsvorschrift

The title compound was synthesized according to the method of Example A51B, except reacting (1R,2S)-2-(3-iodo-1H-indazol-6-yl)-5′-methoxyspiro[cyclopropane-1,3′-indolin]-2′-one (195 mg, 0.45 mmol) with 1-methyl-4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperidine (150 mg, 0.50 mmol). The reaction was then allowed to cool to rt and was diluted with EtOAc and water was added. The resulting mixture was extracted with EtOAc and the combined organic extracts were washed with brine, dried over MgSO4 and concentrated to give an orange solid. The title compound was purified by silica gel chromatography (95:3:2 to 80:18:2 CH2Cl2/MeOH/NH3) to yield a yellow solid. HCl (1M in diethyl ether, 0.15 mL, 0.15 mmol) was added in a dropwise manner to a solution of (1R,2S)-5′-methoxy-2-(3-(4-(1-methylpiperidin-4-yl)phenyl)-1H-indazol-6-yl)spiro[cyclopropane-1,3′-indolin]-2′-one in THF (2 mL). A brown precipitate formed and the solid was then filtered and freeze-dried to give the title compound as a white solid (43 mg, 17%). 1H NMR (400 MHz, CD3OD) δ 7.95-7.92 (m, 3H), 7.52 (s, 1H), 7.44 (d, J=8.0 Hz, 2H), 7.05 (d, J=8.5 Hz, 1H), 6.83 (d, J=8.1 Hz, 1H), 6.62 (d, J=8.7 Hz, 1H), 5.61 (s, 1H), 3.67-3.64 (m, 2H), 3.40-3.32 (m, 1H), 3.27 (s, 3H), 3.21 (t, J=12.8 Hz, 2H), 3.04-2.93 (m, 1H), 2.96 (s, 3H), 2.28-2.19 (m, 4H), 2.07-1.98 (m, 2H); MS ESI 479.4 [M+H]+, calcd for [C30H30N4O2+H]+ 479.24. Optical Rotation: [α]22D=127° (c 0.37, MeOH).
