実験手順

Diisopropylethylamine (60 μl, 0.339 mmoles) and a solution of 4-(4′-difluoromethoxy-biphenyl-4-ylaminomethyl)-5-methyl-furan-2-carboxylic acid (171) (50 mg, 0.103 mmoles) in N,N-dimethylformamide (11.0 ml) were added to a stirred solution of 3,5-dimethyl-isoxazole-4-sulphonic acid amide (55 mg, 0.308 mmoles) in N,N-dimethylformamide (5.0 ml). A solution of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (46 mg, 0.124 mmoles) in N,N-dimethylformamide (11.0 ml) was added and the mixture was stirred at room temperature for 16 hours. The reaction mixture was concentrated in vacuo and the residue was purified by HPLC to afford compound 174 (2 mg) as a solid. LC/MS System D; Rt=10.35 mins, m/z (ES+)=532 (M+H for C25H23F2N3O6S).
