実験手順

A solution 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 (0.1 g, 0.19 mmol) in trifluoroacetic acid (15 mL) and platinum oxide (0.1 g) were combined and hydrogenated overnight on a Parr apparatus. The reaction mixture was filtered to remove the catalyst. The filtrate was concentrated under vacuum. The residue was dissolved in dichloromethane. The dichloromethane solution was washed twice with 10% sodium hydroxide and with brine, dried and then concentrated under vacuum to provide crude product. This material was purified by chromatography eluting with 10% methanol in dichloromethane. The resulting oil was triturated with acetonitrile to provide 0.05 g of N1-[2-(4-amino-2-butyl-6,7,8,9-tetrahydro-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. 208-210° C. Analysis: Calculated for C30H44N6O2+0.1 CF3CO2H: %C, 68.17; %H, 8.35; %N, 15.79; Found: %C, 68.48; %H, 8.29; %N, 16.08.
