실험 절차

979 mg (2.45 mmol, 3 eq) of resin-supported borohydride and 11 mg (0.02 mmol, 0.03 eq) of bis(bipyridine)dibromonickel (II) are added to a solution of 244 mg (1.22 mmol, 1.5 eq) of 5-heptyl-4-methyl-4H-[1,2,4]-triazole-3-thiol in 4 ml of tetrahydrofuran/ethanol 5/5. To the suspension obtained there is added a solution of 405 mg (0.82 mmol, 1 eq) of [4-(2-heptyloxy-4-iodobenzyloxy)phenyl]acetic acid methyl ester in 4 ml of tetrahydrofuran/ethanol 5/5. The reaction mixture is stirred overnight under reflux. After returning to room temperature, the reaction medium is filtered and then concentrated. The residue is chromatographed on silica gel (heptane/ethyl acetate: gradient from 70/30 to 50/50). After concentration, 427 mg (92%) of the expected compound are obtained.
