50 °C

Ten grams of 8-amino-2-naphthol were added to a mixture of acetic anhydride/formic acid (40 mL:20 mL). The mixture was warmed at 50° C. for one hour and then quenched on ice. After stirring for some time, the product solidified and was filtered off. Recrystallization from ethanol gave 6 g of 8-formamido-2-naphthol melting at 203°-205° C.
