実験手順

309 mg of (2S,3S)3-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)2-hydroxy-4-phenylbutyraldehyde and 238 mg of N-tert.butyl-decahydro-(4aS,8aS)-isoquinoline-3(S)-carboxamide are dissolved in 5 ml of acetic acid and treated portionwise with 120 mg of sodium cyanoborohydride. After completion of the reaction the mixture is concentrated to dryness, treated with 10 ml of water and extracted with methylene chloride. The extracts are dried and filtered, the filtrate is concentrated and the residue is purified on silica gel with methylene chloride/methanol (95:5). N-tert.Butyl-decahydro-2-[2(R)-hydroxy-4-phenyl-3(S)-phthalimidobutyl]-(4aS,8aS)-isoquinoline-3(S)-carboxamide is obtained.
