2,4-Dinitro-1-[4-(octyloxy)phenoxy]benzene → HCID 22665187, compound

Participants

Reaction Steps

The resultant 1-[4-(2,4-dinitrophenoxy)phenoxy]octane (31.08 g, 0.080 mol) and ethanol (700 ml) and 10% Pd/C (1.50 g) were introduced into a 2-liter (l) reaction bottle. After hydrogen passed through the reaction under normal pressure for 4 hours, the reaction mixture was filtered and concentrated to obtain a crude product. The crude product was recrystallized by ethanol to obtain 1-[4-(2,4-diaminophenoxy)phenoxy]octane (22.33 g, 0.068 mol). Yield: 85%.
