This compound was prepared according to the method described in Example 2 by employing 4-chloro-2-methyl-6-phenylpyrrolo[3,2-d]pyrimidine (Example 1(e)) (70 mg, 0.29 mmol), N,N′-dimethylethylenediamine (Aldrich Chemical Company) (0.15 mL, 1.44 mmol) and K2CO3 (0.40 g, 2.87 mmol) in H2O (2 mL). The crude material was purified by flash chromatography on silica gel with 9:1 CHCl3:MeOH as eluant to give 18.5 mg (22%) of the title compound as an off-white solid. An analytical sample was obtained by recrystallization from EtOH. 1H NMR (CDCl3; 400 MHz): δ 2.60 (s, 6), 3.04 (t, 2, J=4.5), 3.15 (s, 3), 3.75 (t, 2, J=4.5), 6.76 (s, 1), 7.31-7.42 (m, 3), 7.70 (d, 2, J=7.4). MS m/z: 296 (M+1), 294 (M−1). HRMS: Calcd for M+H: 296.1875. Found: 296.1884.
