Versuchsvorschrift

To a 0° C. cooled solution of (E)-4-fluoro-N-(6-(hydroxymethyl)-1-(cis-4-isobutyramidocyclohexyl)-1H-benzo[d]imidazol-2(3H)-ylidene)benzamide (75 mg, 0.166 mmol) in DCM (5 mL) was added thionyl chloride (0.060 mL, 0.829 mmol) dropwise. The resulting mixture was stirred at 0° C. for 30 minutes. After 30 minutes, the solvent was removed, and the residue was suspended in ACN (5 mL) and re-concentrated to remove residual thionyl chloride. The residue was resuspended in ACN (3 mL), cooled to 0° C., and 2-(piperidin-4-yl)propan-2-ol (95 mg, 0.663 mmol) was added. The reaction was stirred overnight at RT. After 16 hours, the reaction mixture was concentrated and partitioned between EtOAc and water. The organic layer was concentrated and the residue was purified by column chromatography, eluting with 0-100% (90:9:1 DCM/MeOH/NH4OH) in DCM to provide (E)-4-fluoro-N-(6-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-1-(cis-4-isobutyramidocyclohexyl)-1H-benzo[d]imidazol-2(3H)-ylidene)benzamide as a white powder (30 mg, 31.3% yield). MS, m/z (C33H44FN5O3): calcd, 577.3. found, 578.1 [M+H].
