関与物質

反応手順

A suspension of 3.0 gm (19.6 mMol) 6-amino-3-nitro-2-picoline in 50 mL water containing 3.5 mL concentrated sulfuric acid was heated to effect solution. The resultant solution was cooled to 0° C. and a solution of 2.0 gm (29.4 mMol) sodium nitrite in 10 mL water was added with vigorous stirring at a rate to maintain the reaction mixture ≤10° C. After 4 hours the reaction mixture was filtered. The solid was washed with water and dried under reduced pressure to provide 2.4 gm (80%) of the desired compound as a pale yellow solid.
