实验过程

As shown in Scheme 2, a mixture of intermediate 1 of Scheme 2 (16 mg) and N1-isopropyl-3-methoxybenzene-1,4-diamine (15 mg, prepared from WO 2006/021548) in dioxane (1.0 mL) with catalytic trifluoroacetic acid was stirred overnight at 50° C. The crude was concentrated under reduced pressure and purified using HPLC (TFA modifier) to give the title compound (8 mg) as a TFA salt. 1H-NMR (DMSO-d6, 400 MHz) δ 10.12 (s, 1H), 8.49 (br, 1H), 8.24 (s, 1H), 8.06 (s, 1H), 7.71 (br, 1H), 7.47 (d, J=6.4 Hz, 1H), 7.23 (m, 3H), 6.44 (dd, J=10.0, 16.8 Hz, 1H), 6.23 (m, 2H), 5.91 (m, 1H), 5.75 (dd, J=1.6, 10.0 Hz, 1H), 5.21 (m, 1H), 3.68 (s, 3H), 1.10 (d, J=6.0 Hz, 1H); calculated mass for C24H25F3N6O2: 486.2. found: 486.9 (M+H+).
