実験手順
To a solution 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 (57.4 mg, 0.142 mmol) and diisopropyl ethylamine (49 μl, 0.28 mmol) in acetonitrile (20 ml) at room temperature was added 2-bromomethyl-5-methoxy-isophthalic acid dimethyl ester (3.00 g, 7.45 mmol). The solution was stirred for 16 hours and the solvent evaporated in vacuo. The residue was taken into ethyl acetate (50 ml) and washed with water (2×20 ml), 1 N hydrochloric acid (20 ml), brine, dried (MgSO4), filtered and the solvent evaporated in vacuo. The residue was chromatographed on silica gel column using a mixture of ethyl acetate/hexane (1:1) as eluent, which afforded 62 mg (71%) of 2-amino-6-(4-methoxy-benzyl)-5-(6-methoxy-4-methoxycarbonyl-1-oxo-1,3-dihydro-isoindol-2-ylmethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester as a solid.
