Participants

Reaction Steps

Using the general method of Example 97 6-hydroxypicolinic acid (0.24 g, 1.7 mmole) was reacted with 2-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethaneamine (0.5 g, 1.7 mmol) to provide 0.15 g of N-[2-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-6-hydroxy-2-pyridinecarboxamide as a white powder, m.p. 258-260° C. Analysis: Calculated for C21H23N7O2+½CH3CN: %C, 62.03; %H, 5.80; %N, 24.66; Found: %C, 61.87; %H, 5.70; %N, 24.60.
