実験手順

To a suspension of 0.060 g (0.18 mmol) of 5-(3-benzofuran-2-yl-phenyl)-1,4-dimethyl-1H-pyrazole-3-carboxylic acid in 2 ml of CH2Cl2 was added 0.031 g (0.22 mmol) of 2-(1,4-diazepan-1-yl)ethan-1-ol, diluted in 1.7 ml of CH2Cl2. This solution was treated at 0° C. with 0.048 g (0.23 mmol) of DCC. The reaction was allowed to warm up over night to RT, then partitioned between aqueous saturated NaHCO3/EtOAc (3×). The organic phases were washed with aqueous saturated NaHCO3, dried (Na2SO4) and evaporated. The residue was suspended in EtOAc and filtered to remove the DCC urea. Purification by flash chromatography (SiO2—NH2, n-heptane/EtOAc 1:4) gave 0.033 g (39%) of [5-(3-benzofuran-2-yl-phenyl)-1,4-dimethyl-1H-pyrazol-3-yl]-[4-(2-hydroxy-ethyl)-[1,4]diazepan-1-yl]-methanone as white oil. MS: 459.3 (MH+).
