실험 절차

A solution of ethyl [4-(2-heptyloxy-4-iodo benzylamino)phenyl]acetate obtained in Step d (4.11 g, 8.07 mmol) in a mixture of tetrahydrofuran (THF) (18 ml) and ethanol (18 ml) is added dropwise to a mixture of 5-(4-tert-butylphenyl)-4-methyl-4H-[1,2,4]-triazole-3-thiol (2.99 g, 12.1 mmol), bis(bipyridine)nickel (II) bromide (106 mg, 0.2 mmol) (Organometallics, 4, (1985), 657-661) and 9.68 g of borohydride polymer supported on Amberlite® IRA400 resin at 2.5 mmol/g (Aldrich) in 18 ml of a mixture of THF and ethanol 50:50. The mixture is heated for 20 hours under reflux, and then filtered at room temperature. The filtrate is concentrated using a rotary evaporator. The product is purified by chromatography on a silica column, eluted with a heptane/ethyl acetate 7:3 mixture. After evaporation of the solvents, 4.58 g (90%) of the expected compound are recovered in the form of an oil.
