実験手順

To a solution of 3-[3-(S)-(4,6-dichlorobenzo[b]thiophene-2-sulfonylamino)-2-oxo-pyrrolidin-1-ylmethyl]-benzamidine trifluroacetate (0.25 g, 0.40 mmol), prepared as in EXAMPLE 14, Part E, in 4 mL of CH2Cl2 :DMF (10:1) is added N-methyl piperidine (0.12 g, 1.2 mmol) followed by trichloroethyl chloroformate (0.93 g, 0.44 mmol). The solution is stirred for 16 hours. After this time, the solution is diluted with EtOAc. The organic layer is washed with 1N HCl, H2O, saturated NaCl. The organic layer is dried over MgSO4, filtered and concentrated. The residue is purified by column chromatography eluting with a gradient of 1% MeOH/CH2Cl2 to 3% MeOH/CH2Cl2 to afford the title compound (0.20 g, 0.30 mmol) as a white solid.
