实验过程

1.48 g of N-tert.-butyl-2-dimethylaminocarbonyl-5-methoxycarbonylamino-benzenesulfonamide (Example f) are stirred in 25 ml of trifluoroacetic acid for 18 hours. After the acid has been distilled off, the residue is suspended in toluene. Renewed concentration gives 1.40 g of the sulfonamide; m.p.: 75-77° C.
