Procedure

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 (155 mg, 0.384 mmol) and triethylamine (59 μl, 0.423 mmol) in dichloromethane (2 ml) at 0° C., was added a solution of 3-chloro-benzo[d]isothiazole 1,1-dioxide (85.2 mg, 0.423 mmol) in dichloromethane (2 ml). The reaction mixture was stirred at 0° C. for 1 hour. The reaction was judged complete by tlc (dichloromethane/ethyl acetate (1:1)). The reaction mixture was washed with water (3×20 ml), dried (MgSO4), filtered and the solvent evaporated in vacuo. The crude residue was subjected to flash chromatography using a gradient from 100% dichloromethane to dichloromethane/ethyl acetate (80/20) as eluent, which afforded 200 mg (92%) of 2-amino-5-((1,1-dioxo-1H-benzo[d]isothiazol-3-ylamino)methyl)-6-(4-methoxy-benzyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester as a foam.
