EXAMPLE 2-80 4-Chloro-6-fluoro-3-methyl-1-(2-pyridinyl)-1H-pyrazolo[3,4-b]quinoline Following the procedures described in Reference Example 2-5 and Example 2-1, the title compound was prepared from 5-fluoro-2-iodobenzoic acid and 3-methyl-1-(2-pyridinyl)-1H-pyrazol-5-ylamine (57% yield). mp: 185-187 C. (recrystallized from ethyl acetate). NMR (DMSO-d6) delta: 3.00 (3H, s), 7.21-7.28 (1H, m), 7.62 (1H, ddd, J=3.0 Hz, 5.4 Hz, 9.4 Hz), 7.89-7.99 (2H, m), 8.19 (1H, dd, J=5.4 Hz, 9.4 Hz), 8.69 (1H, d, J=3.6 Hz), 8.77 (1H, d, J=8.2 Hz).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Fluoro-2-iodobenzoic acid, its application will become more common.
