Reaction Steps

Using the general method of Example 97 3,5-dimethylisoxazole-4-carboxylic acid (0.25 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 0.23 g of N-[2-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-3,5-dimethyl-4-isoxazolecarboxamide as a white powder, m.p. 188-189° C. Analysis: Calculated for C21H25N7O2: % C, 61.90; % H, 6.18; % N, 24.06; Found: % C, 61.92; % H, 6.15; % N, 24.28. HRMS (EI) calcd for C21H25N7O2 (M+) 407.2069 found 407.2068
