Reaction Steps

A solution of 6-iodo-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine (prepared as in Example 1, 400 mg, 1.23 mmol) in tetrahydrofuran (20 mL) at 25° C. was treated with sodium hydroxide (98 mg, 2.46 mmol), methyl iodide (0.09 mL, 1.48 mmol), and tetrabutylammonium bromide (198 mg, 0.62 mmol and stirred at 25° C. for 18 h. The resulting mixture was treated with ethyl acetate, water, and a saturated aqueous sodium chloride solution, shaken and separated. The aqueous layer was extracted with ethyl acetate and the combined organic layers were dried over sodium sulfate, filtered, and concentrated in vacuo to afford 6-iodo-7-methyl-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine (500 mg) as a yellow solid. The product was taken on into the next reaction without further purification.
