実験手順

To an N,N-dimethylformamide (1 mL) solution of the compound (80 mg) obtained in Example 32(5), 2-hydroxy-N,N-dimethylacetoamide (CAS Registry Number: 14658-93-6; 77 mg), diisopropylethylamine (39 μL) and N,N,N′,N′-tetramethyl-O-(7-azobenzotriazol-1-yl)uronium hexafluorophosphate (86 mg) were added. The reaction solution was stirred at room temperature for 16 hours. To this solution, an aqueous saturated sodium hydrogen carbonate solution was added, and the solution was extracted with ethyl acetate. The organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (CHROMATOREX NH (trade name), manufactured by Fuji Silysia Chemical Ltd.) (ethyl acetate:methanol=1:0→30:1→15:1) to obtain the title compound (68 mg) having the following physical properties.
