実験手順

21.1 g (77 mmol) of 2-acetyl-1,2,3,4-tetrahydroisoquinoline-7-sulfonyl chloride (prepared as described in G. Grunewald et al. J. Med. Chem 1999, 42, 118-134) in 50 ml of THF were added dropwise to a solution of 6.0 g (70 mmol) of piperidine and 10.9 g (84 mmol) of diisopropylethylamine in 230 ml of THF, and the mixture was heated under reflux for two hours. After the reaction was complete, the solvent was removed in vacuo, the residue was taken up in dichloromethane/water and, after making alkaline with 10% strength sodium hydroxide solution and separating the phases, the organic phase was dried over sodium sulfate. The crude product remaining after filtration and removal of the solvent was purified by column chromatography on silica gel (mobile phase: methylene chloride with 3% methanol).
