Reaction Steps

To a mixture of 4-chloro-2-methyl-6-phenylpyrrolo[3,2-d]pyrimidine (Example 1(e)) (85.0 mg, 0.35 mmol) and 2-methylbenzyl amine (Aldrich Chemical Company) (2.2 mL, 17.4 mmol) was added a solution of K2CO3 (0.35 g, 2.54 mmol) in H2O (2.5 mL). This mixture was stirred at 140° C. in a closed-capped Wheaton vial for 1.5 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) and then recrystallized from MeOH/CH2Cl2 to give 42 mg (35%) of the title compound as a white solid. Mp: 277-281° C. MS m/z: 329 (M+1). 1H NMR (DMSO-d6; 400 MHz): δ 2.38 (s, 3), 2.42 (s, 3), 4.69 (d, 2, J=4.8), 6.75 (s, 1), 6.98 (br t, 1), 7.19-7.25 (m, 3), 7.35-7.42 (m, 2), 7.49 (t, 2, J=7.8), 7.76 (d, 2, J=7.8), 11.27 (s, 1). Anal. Calcd for C21H20N4: C, 76.83; H, 6.10; N, 17.07. Found: C, 76.58; H, 6.20; N, 16.94.
