Reaction Steps

To a heated (45° C.), stirred solution of 2-cyano-6-methylphenol (5 g) in glacial acetic acid (32 mL) was added a solution of fuming nitric acid (3.2 mL) in acetic acid (12 mL). After 1 h at elevated temperature (45° C.), the reaction mixture was cooled (to 0° C.), water added and partitioned between DEE/water. The organic phase was washed with water, brine, dried over sodium sulfate and concentrated in vacuo to afford a solid. Recrystallization from DEE afforded the title compound as yellow crystals (3.6 g).
