실험 절차

A solution of 2-amino-4,7-dihydro-5H-thieno[2,3-c]pyridine-3,5-(S),6-tri-carboxylic acid 3,6-di-tert-butyl ester (0.30 g, 0.75 mmol) and triethylamine (0.21 mL, 1.51 mmol) in tetrahydrofuran (10 mL) was cooled to −20° C. before isobutyl chloroformate (103 μL, 0.75 mmol) was added. The reaction mixture was stirred 15 min at −20° C. before homocystein hydrochloride (116 mg, 0.75 mmol) was added. The cooling bath was removed and the reaction mixture was left for 16 hours at room temperature. The solvent was removed in vacuo and the residue was subjected to column chromatography (SiO2, Flash 40, heptane/ethyl acetate 2:1) to give 212 mg (56%) of 2-amino-5-(S)-(2-oxo-tetrahydro-thiophen-3-ylcarbamoyl)-4,7-dihydro-5H-thieno[2,3-c]pyridine-3,6-dicarboxylic acid di-tert-butyl ester
