To a mixture of 4-chloro-2-methyl-6-phenylpyrrolo[3,2-d]pyrimidine (Example 1(e)) (47.6 mg, 0.19 mmol) and 5-methyl-2-furanmethanamine (Acros Chemical Company) (100 μL, 0.98 mmol) was added a solution of K2CO3 (0.11 g, 0.76 mmol) in H2O (1.5 mL). This mixture was stirred at 140° C. in a closed-capped Wheaton vial for 2.5 h. After cooling, CH2Cl2 (10 mL) and H2O (10 mL) were added. The organic solution was removed and the aqueous solution washed with CH2Cl2 (10 mL). The combined organic solutions were washed with saturated NaCl (15 mL), dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (3% MeOH:CHCl3 on silica gel) to give 37 mg (62%) of the title compound as a beige solid. Mp: 125-127.5° C. MS m/z: 319 (M+1), 294, 225, 195, 147. 1H NMR (CD3OD, 400 MHz): δ 2.28 (s, 3), 2.53 (s, 3), 4.72 (s, 2), 5.97 (d, 1, J=3.0), 6.24 (d, 1, J=3.0), 6.66 (s, 1), 7.34 (m, 1), 7.43 (t, 2, J=7.7), 7.71 (dd, 2, J=7.1, 1.4). HRMS: Calcd for M+H, C19H18ON4: 319.1555. Found: 319.1566.
