Procedure

Under a nitrogen atmosphere, isopropyl isocyanate (206 μL, 2.10 mmol) was added to a chilled (0° C.) solution of 1-(2-amino-2-methylpropyl)-2-ethoxymethyl-1H-imidazo[4,5-c][1,5]naphthyridin-4-amine (628 mg, 2.00 mmol) in dichloromethane (20 mL). The reaction mixture was allowed to warm slowly to ambient temperature overnight. The resulting precipitate was isolated by filtration and then dried under vacuum at 70° C. to provide 669 mg of 1-[2-(4-amino-2-ethoxymethyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)-1,1-dimethylethyl]-3-(1-methylethyl)urea as white powder, mp 172.5-173.5° C. Anal. calcd for C20H29N7O2: % C, 60.13; % H, 7.32; % N, 24.54. Found: % C, 59.88; % H, 7.55; % N, 24.51.
