Reaction Steps

To a mixture of 4-chloro-2-methyl-6-phenylpyrrolo[3,2-d]pyrimidine (Example 1(e)) (88.3 mg, 0.36 mmol) and N-(2-piperidylmethyl)-dimethylamine (Salor Chemical Company) (0.25 g, 1.72 mmol) was added a solution of K2CO3 (0.25 g, 1.60 mmol) in H2O (2.5 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 was 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 43 mg (34%) of the title compound as a yellow oil. MS m/z: 350 (M+1), 305, 214. 1H NMR (DMSO-d6; 400 MHz): δ 1.63 (m, 6), 2.29 (s, 6), 2.40 (s, 3), 2.81 (m, 2), 3.03 (br t, 1, J=11.8), 4.53-4.63 (m, 2), 6.75 (s, 1), 7.37 (m, 1), 7.50 (t, 2, J=7.5), 7.81 (d, 2, J=7.8), 12.47 (s, 1).
