実験手順

A stirring solution of 5-(4-fluoro-phenyl)-2-hydroxymethyl-thiazole-4-carboxylic acid (320 mg, 1.0 mmol, 80% pure) and (RS)-4,5-difluoro-2-piperidin-2-ylmethyl-1H-benzoimidazole, D21 (250 mg, 1.0 mmol) in DMF (10 ml) was treated with EDC.HCl (194 mg, 1.0 mmol) and 1-hydroxybenzotriazole (50 mg, 0.4 mmol). The reaction mixture was stirred at room temperature, under argon for 16 h. The resulting solution was diluted with diethyl ether then washed with saturated aqueous NaHCO3, water (3×) and brine. Drying (MgSO4) and removal of the solvent in vacuo afforded an orange gum. Chromatography (silica gel, 0-2% methanol-dichloromethane) afforded the title compound as an orange powder (160 mg, 33%). Mass spectrum (Electrospray LC/MS) Found 487 (MH+). C24H21F3N4O2S requires 486.
