Procedure

To a solution of 2-amino-5-aminomethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylic acid tert-butyl ester (101 mg, 0.35 mmol) in dichloromethane (1 ml) was added pyridine (32 μl, 0.39 mmol) and 4-methoxybenzenesulfonyl chloride (82 mg, 0.39 mmol). The reaction mixture was stirred at room temperature for 48 h. The reaction mixture was diluted with dichloromethane (2 ml) and subjected to preparative TLC (1:1 hexanes/ethyl acetate) affording 10 mg, (10%) of 2-amino-5-((4-methoxy-benzenesulfonylamino)-methyl)-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxylic acid tert-butyl ester as a solid.
