Procedure

A stirred mixture of (1R,2R)-2-((6-((5-bromo-7-fluoro-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (150 mg, 0.316 mmol) from Example 203, zinc cyanide (111 mg, 0.948 mmol), 1,1′-bis(diphenylphosphino)ferrocene (35 mg, 0.0632 mmol) and anhydrous DMF (2 mL) was purged with a stream of argon. To the mixture was added palladium(trisdibenzylideneacetone) (0) (29 mg, 0.0316 mmol) and the mixture was heated in a sealed tube 100° C. for 6 h. The mixture was cooled and additional zinc cyanide (111 mg, 0.948 mmol), 1,1′-bis(diphenylphosphino)ferrocene (35 mg, 0.0632 mmol), and palladium(trisdibenzylideneacetone) (0) (29 mg, 0.0316 mmol) were added, and heating in a sealed tube was continued at 100° C. for 15 h. The mixture was cooled to rt and purified directly by reverse-phase preparative HPLC using a mixture of water (5% CH3CN, 0.05% HOAc) and CH3CN (0.05% HOAc) as the mobile phase and Varian Pursuit XRs diphenyl column as the stationary phase to afford (7-fluoro-1-((2-(((1R,2R)-2-hydroxycyclohexyl)amino)benzo[d]thiazol-6-yl)methyl)-1H-benzo[d]imidazole-5-carbonitrile (2.6 mg, 2%) as a white solid. 1H NMR (500 MHz, DMSO-d6) δ 8.70 (s, 1H), 8.13 (s, 1H), 8.02 (d, J=7.6 Hz, 1H), 7.63 (d, J=11.1 Hz, 1H), 7.57 (s, 1H), 7.29 (d, J=8.1 Hz, 1H), 7.10 (d, J=8.1 Hz, 1H), 5.58 (s, 2H), 4.77 (br s, 1H), 3.50 (br m, 1H), 3.30 (br m, 1H), 2.02 (m, 1H), 1.87 (m, 1H), 1.55-1.67 (m, 2H), 1.12-1.32 (m, 4H); LCMS (ESI) m/z 422 (M+H)+.
