The alkalinity is preferably adjusted to 9 to 11, and the reaction is carried out at a temperature of 0 DEG C. or higher, preferably from room temperature to the boiling point of the solvent, until the reaction is completed, for example, for 5 to 48 hours. There are no particular restrictions on the solvent used, as long as it is an organic solvent that mixes uniformly with water.

When dimethylpyrazole is used, it can be carried out in the same manner as the above-mentioned O-methylisourea and S-methylthiourea, but other non-aqueous systems can also be used. In other words, the solvent is not particularly limited as long as it is an organic solvent that does not participate in the reaction, but lower alcohols such as methanol, ethanol, and propanol, ethers such as dimethyl ether, dioxane, and tetrahydrofuran, esters such as ethyl acetate, and ketones such as acetone can be used as the solvent. , halogenated hydrocarbons such as chloroform and methylene chloride, amides such as dimethylformamide, and nitriles such as acetonitrile, etc., and organic bases such as triethylamine and diisopropylethylamine may be used as the base. The reaction temperature is 0° C. or higher, preferably in the temperature range from room temperature to the boiling point of the solvent. The reaction time is not particularly limited and may be carried out until the reaction is completed, which is usually completed by stirring the reaction for 5 to 24 hours.

The reaction is preferably carried out at a temperature ranging from room temperature to the boiling point of the solvent. The reaction usually reaches steady state in 1 to 12 hours. If raw materials remain, the reaction can be accelerated by adding an acid and preferably adjusting the pH to 3 to 5. The solvent to be used is not particularly limited, but water or a water-containing solvent such as an organic solvent that mixes uniformly with water, or a non-aqueous solvent containing only an organic solvent may be used.
