Reaction Steps

A stirred mixture of 2-bromo-6-((5,6-dimethoxy-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazole (70 mg, 0.173 mmol) from Example 2, cyclohexanemethylamine (39 mg, 0.346 mmol) and DIEA (67 mg, 0.519 mmol) in anhydrous DMA (1.5 mL) was heated at 100° C. for 2.5 h. After cooling to rt, the mixture was purified directly by reverse-phase HPLC using a mixture of water (5% CH3CN, 0.05% HCOOH) and CH3CN (0.05% HCOOH) as the mobile phase and Varian Pursuit XRs C-18 column as the stationary phase to afford N-(cyclohexylmethyl)-6-((5,6-dimethoxy-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-amine (25 mg, 33%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 8.15 (br s, 1H), 8.04 (t, J=5.4 Hz, 1H), 7.63 (s, 1H), 7.31 (m, 1H), 7.12-7.24 (m, 3H), 5.40 (s, 2H), 3.76 (s, 6H), 3.17 (t, J=6.1 Hz, 2H), 1.49-1.78 (m, 6H), 1.07-1.27 (m, 3H), 0.84-1.02 (m, 2H). LCMS (ESI) m/z 437 (M+H)+.
