Procedure

To a 5-mL Wheaton vial was added 4-chloro-2,6-dimethylpyrrolo[3,2-d]pyrimidine (Example 46(d)) (0.10 g, 0.55 mmol) and morpholine (Aldrich Chemical Company) (0.24 mL, 2.7 mmol). A solution. of K2CO3 (0.35 g, 2.5 mmol) in water (2.5 mL) was added and the reaction mixture heated in the capped vial at reflux for 3.5 h. The reaction mixture was cooled to room temperature and the solution was filtered. The resulting precipitate was washed with H2O and hexanes and dried in a 60° C. vacuum oven to give 0.083 g (65%) of the title compound as an off-white solid. Mp: 242-243° C. 1H NMR (DMSO-d6; 500 MHz): δ 2.39 (s, 6), 3.60 (s, 4), 3.74 (s, 4), 6.07 (s, 1), 10.90 (s, 1). MS m/z: 233 (M+1). Anal. Calcd for C12H16N4O: C, 59.73; H, 7.10; N, 23.22. Found: C, 60.01; H, 6.84; N, 23.29.
