実験手順

Dissolve 2-carboxy-2-[(acetylthio)methyl]-1,2,3,4-tetrahydronaphthalene (2.88 g, 10.0 mmol) in dry dimethylformamide (20 mL). To this solution add N-methyl morpholine (1.01 g, 10.0 mmol), isoserine benzyl ester tosylate salt (3.67 g, 10.0 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (1.92 g, 10.0 mmol). Stir the reaction mixture for 18 hours under an atmosphere of argon at ambient temperature then partition between ethyl acetate and dilute HCl. Wash the organic solution with water, saturated sodium hydrogen carbonate then brine. Dry the solution (MgSO4) and concentrate in vacuo. Purify the residue by column chromatography (ethyl acetate:hexane) to give the title compound.
