Reaction Steps

3-Fluoro-N-[4-methyl-3-(9H-pyrimido[4,5-b]indol-7-yl)phenyl]-5-(trifluoromethyl)-benzamide (0.030 g, 0.064 mmol) was mixed with 1H-imidazole-4-carbaldehyde (0.031 g, 0.32 mmol) and potassium carbonate (0.045 g, 0.32 mol) in DMF (0.7 mL) and was heated at 120° C. for 16 hours. The reaction was then diluted with THF and was filtered and the filtrate was concentrated in vacuo. The residue was purified by prep. LC to give the product (14 mg, 33% yield). 1H NMR (DMSO-d6): δ 13.13 (brs, 1H), 10.57 (s, 1H), 9.84 (s, 1H), 9.67 (s, 1H), 9.16 (s, 1H), 8.88 (d, 1H), 8.71 (d, 1H), 8.62 (m, 1H), 8.44 (m, 1H), 8.40 (d, 1H), 8.29 (m, 1H), 7.75 (m, 2H), 7.58 (s, 1H), 7.47 (m, 1H), 7.39 (m, 1H), 2.27 (s, 3H). MS (EI) m/z=541 (M+H).
