A stirred solution of the above benzamide (100 mg, 0.54 mmol) in dry MeCN (4 mL) was treated with aziridine (168 μL, 3.24 mmol) at room temperature for 4 h. The resulting precipitate was collected, washed with cold water, and crystallized twice from EtOAc to give 9 (46 mg, 41%). mp 223-224° C.;; 1H NMR [(CD3)2SO] δ8.21 (br s, 1H, NHH), 7 99 (d, J=8.5 Hz, 1H, H-5), 7.69 (d, J=1.8 Hz, 1H, H-2), 7.67 (br s, 1H, NHH), 7.56 (dd, J=8 5, 1.8 Hz, 1H, H-6), 2.30 (s, 4H, (CH2)2). Anal. Calcd for C9H9N3O3: C, 52.17;H, 4.38, N, 20.28. Found C, 52 10;H, 4.30, N, 20.07%.
