실험 절차

The compound ([3]-(32)-587) (0.99 g) prepared in Example 36 was dissolved in dry N,N-dimethylformamide (19 ml), and 50% sodium hydride (0.20 g) was added to the solution. The mixture was stirred at room temperature for 15 minutes. A solution of N-(triphenylmethyl)-5-[4'-(bromomethyl)biphenyl-2-yl]tetrazole (2.19 g) in N,N-dimethylformamide (6.5 ml) was added to the solution. The mixture was stirred at room temperature for 39 hours. The reaction mixture was added to water (50 ml), and extracted with chloroform (100 ml). The organic layer was washed, dried over anhydrous sodium sulfate, and concentrated to obtain the compound (2.72 g) as a light yellow solid. The product was purified by silica gel column chromatography (Kieselgel 60=190 g, chloroform/ethyl acetate=7/3) to obtain the compound ([3]-(33)-587) (1.41 g)
