Versuchsvorschrift

tert-Butyl 3-[(3-amino-5,6-dimethyl-2-phenoxypyridin-4-yl)amino]propylcarbamate (68.8 g, 178 mmol), prepared as described in U.S. Pat. No. 6,545,016, Example 17, Parts A through C, was dissolved in chloroform (600 mL). Ethyl 2-chloroacetimidate hydrochloride (56.0 g, 354 mmol) was added to the solution and the reaction mixture was stirred at 60° C. for 72 hours. The reaction mixture was diluted with chloroform (200 mL), washed with brine (2×600 mL), and the layers were separated. The combined organics were dried over magnesium sulfate, filtered through CELITE filter aid, and concentrated under reduced pressure to afford 91.62 g of tert-butyl 3-[2-(chloromethyl)-6,7-dimethyl-4-phenoxy-1H-imidazo[4,5-c]pyridin-1-yl]propylcarbamate.
