1-[(4-Amino-2-propyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)methyl]cyclopropanol was prepared according to the general methods of Parts D through G of Example 84 using 1-(aminomethyl)cyclopropanol in lieu of 1-(2-aminoethyl)cyclopropanol in Part D, 4-chloro-3-nitronaphthyridine in lieu of 4-chloro-3-nitroquinoline in Part D, and trimethyl orthobutyrate in lieu of triethyl orthopropionate in Part F. The crude product was triturated with hot acetonitrile to provide a tan solid. Which was recrystallized from chloroform and hexanes and dried at 140° C. under vacuum to provide product as an off-white solid, mp 199-200° C. MS (ESI) m/z 298 (M+H)+; Anal. calcd for C16H19N5O: C, 64.63; H, 6.44; N, 23.55. Found: C, 64.32; H, 6.62; N, 23.67.
