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-ethyl-2-methylallylamine (Aldrich Chemical Company) (0.19 mL, 1.44 mmol) and K2CO3 (0.397 g, 2.87 mmol) in H2O (2 mL). The crude material was purified by preparative TLC on silica gel with 1:1 EtOAc:hexanes as eluant to give 36.7 mg (42%) of the title compound as off-white solid. An analytical sample was obtained by recrystallization from EtOAc. Mp: 148-150° C. 1H NMR (CDCl3; 500 MHz): δ 1.32 (t, 3, J=7.1), 1.95 (s, 3), 2.59 (s, 3), 3.78 (q, 2, J=7.1), 4.20 (s, 2), 5.18 (s, 1), 5.24 (s, 1), 6.74 (s, 1), 7.35-7.48 (m, 3), 7.55 (d, 2, J=7.4), 8.47 (br s, 1). MS m/z: 307 (M+1), 305 (M−1). Anal. Calcd for C19 H22N4: C, 74.48; H, 7.24; N, 18.28. Found: C, 74.36; H, 7.27; N, 18.19.
