The reaction mixture was concentrated under reduced pressure and the residue was partitioned between DCM and H2O. The separated organics were dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, DCM:MeOH 98:2) and then by preparative HPLC. Product-containing fractions were combined, made basic with a saturated aqueous solution of sodium hydrogen carbonate and CH3CN was removed under reduced pressure. The aqueous phase was extracted with DCM and the separated organics dried over Na2SO4, filtered and concentrated to dryness, affording the title compound (49 mg, 0.16 mmol) as a off-white solid.

实验步骤: To a solution of 0.356 g (1.26 mmol) of N-[2-(3-indolyl)ethyl)]decahydroiso-quinoline in 20 ml of ethanol was added a solution of 1.6 g of mercuric acetate and 1.88 g of ethylenediaminetetra-acetic acid disodium salt dihydrate in 40 ml of water and the resulting mixture was refluxed for 3 h. The cooled mixture was made basic with dilute ammoniumhydroxide (pH 11) and then extracted with dichloromethane (3×30 ml). The combined organic layers were dried over sodium sulfate, filtered and the solvent evaporated to give the crude enamine (mixture of regioisomers), which was directly used in the next step (see example 36). The pure enamine could be obtained by column chromatography (silica gel, dichloromethane/methanol/triethylamine, 98:1:1). the resulting mixture was refluxed for 3 h extracted with dichloromethane (3×30 ml) The combined organic layers were dried over sodium sulfate filtered the solvent evaporated to give the crude enamine (mixture of regioisomers), which

The total amount of hydrogen absorbed during the reaction was 4.9 moles and the molar ratio of the absorbed hydrogen to isoquinoline was 5.3. The reaction mixture obtained after separation of the catalyst by filtration was analyzed by gas chromatography. It was found to contain 88% of decahydroisoquinoline.
