참여 물질

반응 단계

A solution of 2,6-diacetylpyridine (Aldrich Chemical, Milwaukee, Wis., 0.815 g, 5 mmole) in hot ethanol (10 ml) was mixed with a solution of dimethylaminoacethydrazide hydrochloride (Avocado/Alfa Aesar, Ward Hill, Mass.) in warm water (10 ml). The mixture was heated to reflux briefly and allowed to cool. After 3 hrs the mixture was diluted with 20 ml isopropanol, causing a copious precipitate to form. The precipitate was filtered out and washed with isopropanol. Drying gave 2.065 g (95%) white crystalline solid, melting pt. 280-282° C. (dec.).
