実験手順
A stirred solution of 2-nitro-5-fluorobenzamide (Orrin, Eur. Pat. Appl. 19,388; Chem. Abstr. 1981, 94, 156538h) (480 mg, 2.61 mmol) in dry DMSO (2 mL) was treated with aziridine (0.54 mL, 10.4 mmol) at room temperature under N2 for 48 h, then poured into cold water (50 mL). Prolonged cooling at −5° C. gave a crystalline product that was collected and filtered throuhg a column of silica gel in EtOAc to give 11 (256 mg, 47%), mp (EtOAc) 172-174° C. 1H NMR [(CD3)2SO] δ8.01 & 7.61 (2xs, 2H, CONH2), 7.93 (d, J=8.9 Hz, 1H, H-3), 7.17 (dd, J=8.8, 2.4 Hz, 1H, H-4), 7.09 (d, J=2.3 Hz, 1H-6), 2.24 (s, 4H, aziridine-H ). Anal. Calcd. for C9H9N3O3: 52.17;H, 4.38; N, 20.29 Found: C, 52.29;H, 4.27; N, 20.25%.
