Versuchsvorschrift

To a mixture of 2-amino-5-aminomethyl-6-(4-methoxy-benzyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester (300 mg, 0.74 mmol), benzo[1,3]dioxol-5-yl-acetic acid (134 mg, 0.74 mmol), 1-hydroxybenzotriazole hydrate (111 mg, 0.82 mmol), and N,N-diisopropyl-ethylamine (258 μL, 1.48 mmol) in acetonitrile (5 ml) at room temperature was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (157 mg, 0.82 mmol). The reaction mixture was stirred for 16 hours and the solvent evaporated in vacuo. The residue was taken into ethylacetate (50 ml), washed with water, 1 N hydrochloric acid, saturated sodium bicarbonate, brine, dried (MgSO4), filtered and the solvent evaporated in vacuo. The residue was subjected to flash chromatography using a gradient of 10–20% ethylacetate/hexanes as eluent, which afforded 268 mg (64%) of 2-amino-5-((2-benzo[1,3]dioxol-5-yl-acetylamino)methyl)-6-(4-methoxy-benzyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester as an oil.
