Versuchsvorschrift

To a solution of cyclohexyl-[5-fluoro-2-((R)-methoxy-phenyl-methyl)-benzoimidazol-1-yl]-acetic acid (100 mg, 0.25 mmol, 1.0 equiv) in DMF (1.5 mL) was added triethylamine (51.1 mg, 70.0 μL, 0.50 mmol, 2.0 equiv) and HATU (124.7 mg, 0.33 mmol, 1.3 equiv) and the mixture stirred at 40° C. After 15 min, trans-4-amino-cyclohexanol hydrochloride (50.03 mg, 0.33 mmol, 1.3 equiv; [CAS RN 50910-54-8]) was added and stirring continued at 50° C. for 2 h. Removal of the solvent mixture under reduced pressure and purification by preparative HPLC on reversed phase eluting with a gradient of acetonitrile/water provided 50 mg (40%) of the title compound. MS (ISP): 494.5 [M+H]+.
