Procedure

For production of the compound (III), 2-chloro-5-nitrobenzenesulfonyl chloride, i.e. the compound (V), is first reacted with stannous chloride and hydrochloric acid or with zinc and hydrochloric acid or sulfuric acid at a temperature of 40° to 100° C. to give 2-chloro-5-aminothiophenol, i.e. the compound (IV). The amount of the stannous chloride or zinc is usually from 6 to 10 equivalents to the compound (V).
