실험 절차

2.67 g of N-(2-butyl-1-benzofuran-5-yl)methanesulfonamide (II) (0.01 mol, 1 eq) is dissolved in 35 mL of n-hexane and 7 mL of 2.5 M BuLi hexane solution is added in 30 min during which the temperature is kept at 20° C. The reaction mixture is stirred for 2 hours at room temperature and then it is added to the solution of 4.37 g of 4-(3-dibutylamino-propoxy)-benzaldehyde (V) (0.015 mol, 1.5 eq) in 80 mL of THF. The reaction mixture is stirred at room temperature for 2 hours and then 40 mL of NH4Cl solution is added. After 15 min of stirring, the product is extracted with 2×40 mL of diethyl ether. The organic phase is concentrated and the crude product is purified by column chromatography (spheric silica; eluent:toluene:MTBE:methanol=50:40:10) to obtain 2.24 g of compound (VI) (40%).
