実験手順

To a stirred suspension of 4-(6-cyano-4-(methoxycarbonyl)chroman-7-yloxy)benzoic acid (0.10 g, 0.28 mmol), 2-(4-((dimethylamino)methyl)phenyl)ethanamine dihydrochloride (0.056 g, 0.31 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.13 g, 0.34 mmol) in N,N-dimethylformamide (1.4 mL) at ambient temperature was added N, N-diisopropylethylamine (0.25 mL, 1.4 mmol). The resulting solution was stirred at ambient temperature for 60 minutes, then partitioned between water (15 mL) and ethyl acetate (10 mL). The organic layer was dried over sodium sulfate and concentrated. The residue was purified by chromatography on silica gel, eluting with 90/10 chloroform/(90/10 methanol/concentrated ammonium hydroxide), to afford methyl 6-cyano-7-(4-(4-((dimethylamino)methyl)phenethylcarbamoyl)phenoxy)chroman-4-carboxylate as a colorless film (0.083 g, 57% yield).
