3,5-Di-tert-butyl-4-hydroxybenzoyl chloride → N1-[2-(4-amino-2-butyl 1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-3,5-di-(1,1-dimethylethyl)-4-hydroxybenzamide

Participants

Reaction Steps

Using the general method of Example 92, 3,5-di-(1,1 dimethylethyl)-4-hydroxybenzoyl chloride (0.47 g, 1.7 mmol) 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 0.5 g of N1-[2-(4-amino-2-butyl-1H-imidazo[4,5-c][1,5]naphthyridin-1-yl)ethyl]-3,5-di-(1,1-dimethylethyl)-4-hydroxybenzamide as a white powder, m.p. 248–250° C. Analysis: Calculated for C30H40N6O2: % C, 69.74; % H, 7.80; % N, 16.27; Found: % C, 69.65% H, 7.69; % N, 16.42. HRMS (EI) calcd for C30H40N6O2 (M+) 516.3212 found 516.3226.
