실험 절차
The operation is carried out as in Stage 1 of Example 24 using, instead of the hydrochloride of the methyl ester of L-Tryptophan, the hydrochloride of the methyl ester of D-Tryptophan and, instead of (R)-2-(benzoylthio)-3-phenylpropanoic acid, (S)-2-(benzoylthio)-3-phenylpropanoic acid (prepared according the same reference). After purification by chromatography on silica with a methylene chloride-ethyl acetate: 95-5 mixture as eluant, 564 mg of expected product (SR isomer) (colourless foam) is obtained.
