Sodium Carbonate → HCID 21487768, compound

Participants

Reaction Steps

12.6 parts of N-cyclohexylhydroxylamine and 14 parts of sodium carbonate in 125 parts of dioxane and 30 parts of water are placed in a reactor. At 0° to 5° C and over a period of 15 minutes, 17.6 parts of 2-chloronicotinyl chloride in 30 parts of dioxane is dripped into the reaction solution, which is then allowed to after-react for 1 hour. The solution is concentrated and the residue taken up in chloroform, followed by extraction with water, drying and concentration. Crystallization from a mixture of benzene and ligroin yields 15 parts of 2-chloronicotinic acid-N-hydroxy-N-cyclohexylamide, m.p.: 151° to 153° C.
