6-Hydroxy-5-nitro-2-picoline Use and Manufacturing
Synthesis of the compound 25 The compound 24 (10g, 0.065 mol) was added into 100 mL of water, a concentrated sulphuric acid (12 mL) was slowly added with agitation and cooled to 0 °C in an ice bath. Sodium nitrite (6.9 g, 0.098 mol) was added in batches, reacted at 0°C for 4h, and left standing for 12 h. A large amount of yellow precipitate was precipitated, filtrated under the reduced pressure, vacuum-dried to obtain 7.7 g of a yellow product with a yield of 77percent. The melting point is 216.5-218.5°C (water).Synthesis of the compound 25 The compound 24 (10g, 0.065 mol) was added into 100 mL of water, a concentrated sulphuric acid (12 mL) was slowly added with agitation and cooled to 0 °C in an ice bath.
