실험 절차
0.2 g of tert-butyl [4-(5-benzyl[1.3.4]thiadiazol-2-ylcarbamoyl)phenyl]carbamate (0.49 mmol, 1 eq.) is placed in 5 mL of dichloromethane. 1 mL of trifluoroacetic acid (13.54 mmol, 27.6 eq.) is added and the reaction medium is stirred for 3 days at room temperature. The solvents are evaporated off and the residue is taken up in diethyl ether and pentane to give 0.14 g of 4-amino-N-(5-benzyl[1.3.4]thiadiazol-2-yl)-benzamide acid.
