Reaktionsschritte
The foregoing oxadiazole (135 mg, 0.00039 mol) was stirred with trifluoroacetic acid (0.18 mL, 0.0024 mol) in dichloromethane (6 mL) for 24 hours. The hydrogen oxalate salt had mp 134°-135° C. (propan-2-ol). Rf=0.78 in dichloromethane/methanol (9:1) on alumina plates. Mass Spectrum, m/z 242 for M+ of free base. (Found: C, 53.87; H, 4.90; N, 16.52. C13H14N4O. C2H2O4 requires C, 54.21; H, 4.85; N, 16.86%).
