- the method (B) is difficult to carry out industrially because it has a high risk of handling, uses expensive metal sodium, and has a low yield.
- the method (C) requires a long reaction step, and it is necessary to use expensive and highly dangerous perbenzoic acid or trifluoroacetic acid as a reaction reagent.

And a nitro group, a sulfonate group, an alkyl group, an alkoxyl group, a hydroxyl group, a substituted phenylthio group and the like.
- a benzene ring, a pyridin ring, a thiazole ring, and an isothiazole ring having an arbitrary substituent are preferable.
- a benzene ring having a sulfonate group, an alkyl group, an alkoxyl group, a hydroxyl group, and a substituted phenylthio group is more preferable.
- the hydrolysis proceeds simply by adding water and heating, and the aromatic or aromatic compound represented by the general formula (2) is aimed at. Can lead to heteroaromatic thiols.
- This hydrolysis reaction proceeds smoothly in the presence of an acid.
- the acid is not particularly limited, and mineral acids such as hydrochloric acid, sulfuric acid, nitric acid, and phosphoric acid are economically used. Hydrochloric acid and sulfuric acid are particularly preferred.
- the amount of the acid used is usually 0.01 to 1 times the weight of the halogenated methyl sulfide represented by the general formula (1).
- the lower alcohols include methanol, ethanol, isoprono, o-nore, and n-prono. Knol, isobutanol, n-butanol, sec-butanol and the like can be mentioned. Of these, methanol is preferred over economics.
- the amount of the alcohol used is not particularly limited, but is usually 0.5 to 10 times the weight of the halogenated methyl sulfide represented by the general formula (1).
- an aromatic or heterocyclic compound represented by the general formula (3) When an aromatic disulfide is obtained as a target substance, the purpose can be easily achieved by adding an oxidation step after the above-mentioned hydrolysis. That is, an oxidizing agent may be added after the hydrolysis.
- reaction temperature varies depending on the oxidation method and cannot be specified unconditionally, but is usually in the range of about 0 to: L00, preferably about 30 to 90. If the reaction temperature is too low, the reaction rate is slow, and if it is too high, a side reaction occurs, which causes a decrease in yield. Reaction times typically range from about 0.5 to 15 hours.
- the aromatic or heteroaromatic disulfide formed in this way can be easily isolated by crystallization or the like.
