Reaction Steps

20 parts of potassium carbonate in 25 parts of water is added to a solution of 16.9 parts of 2-chloronicotinic acid-N-hydroxy-N-cyclohexylamide in 50 parts of dioxane. At 45° C, 12.6 parts of dimethyl sulfate is dripped into the reaction solution and the whole stirred for 30 minutes at 45° C. The reaction product is precipitated by the addition of water. Crystallization from a mixture of benzene and ligroin yields 14.8 parts of 2-chloronicotinic acid-N-cyclohexyl-N-methoxyamide, m.p.: 96° to 98° C.
