実験手順

To a mixture of (1R*,2S*)-2-(3-iodo-1H-indazol-6-yl)-5′-methoxyspiro [cyclopropane-1,3′-indolin]-2′-one (862 mg, 2 mmol), 4-ethynylbenzaldehyde (286 mg, 2.2 mmol), Pd(PPh3)2Cl2 (28 mg, 0.04 mmol, 2 mmol %) and CuI (15.3 mg, 0.08 mmol, 4 mmol %) in a 50 mL of flask was added DMF (6 mL) and Et3N (10 mL). The resulting mixture was stirred at 100° C. (oil temp.) for 90 min. After removal of Et3N, H2O (20 mL) was added and the precipitates were collected by suction filtration. Crystals formed in the mother liquor were collected and dried to give the title compound (106 mg) as a yellow solid. The remaining residue was combined and purified by flash chromatography (gradient: EtOAc.hex 0 to 50% to 100%), followed by trituration with H2O to give the title compound (440 mg) as a yellow solid. Total 546 mg (yield 63%). 1H NMR (400 MHz, DMSO-d6) δ 13.63 (s, 1H), 10.44 (s, 1H), 10.05 (s, 1H), 7.98 (d, J=7.6 Hz, 2H), 7.87 (d, J=8.0 Hz, 2H), 7.79 (d, J=8.4 Hz, 1H), 7.57 (s, 1H), 7.10 (d, J=8.8 Hz, 1H), 6.75 (d, J=8.4 Hz, 1H), 6.58 (d, J=8.0 Hz, 1H), 5.63 (s, 1H), 3.29 (s, 3H), 3.22 (t, J=8.4 Hz, 1H), 2.40-2.33 (m, 1H), 1.99 (dd, J=8.8 Hz, 4.8 Hz, 1H); MS ESI 434.2 [M+H]+, calcd for [C2H19N3O3+H]+ 434.1.
