Reaction Steps
This compound was prepared according to the method described in Example 26 by employing 4-chloro-2-methyl-6-phenylpyrrolo[3,2-d]pyrimidine (Example 1(e)) (0.10 g, 0.41 mmol), piperazine (Aldrich Chemical Company) (0.382 g, 4.43 mmol) and K2CO3 (0.34 g, 2.50 mmol) in H2O (2.5 mL) to give crude pink solids. These solids were taken up in hot EtOAc, cooled to room temperature, and the impurities were removed by filtration. The filtrate was concentrated to give 0.035 g (29%) of the title compound as an off-white solid. Mp: 236° C. 1H NMR (DMSO-d6; 500 MHz): δ 2.42 (s, 3), 2.85 (t, 4, J=5.2), 3.62 (t, 4, J=5.2), 6.77 (s, 1), 7.36 (m, 1), 7.45 (t, 2, J=7.8), 7.95 (d, 2, J=7.6), 10.96 (s, 1); MS m/z: 294 (M+1). Anal. Calcd for C17H19N5O.0.5 H2O: C 67.53, H 6.67, N 23.16. Found: C 67.35, H 6.59, N 23.01.
