Procedure

In the above embodiments, thionyl chloride (SOCl2), sulphamic acid (NH2—SO2OH) and chlorosulphonic acid (HSO3Cl) were mixed to allow the reaction to proceed in the first step. However, these reactants may be mixed stepwise. For example, sulphamic acid (NH2—SO2OH) is first mixed with thionyl chloride (SOCl2). After the sufficient reaction of the compounds is carried out, chlorosulphonic acid (HSO3Cl) is mixed thereto and subjected to heating. According to this procedure, the desired product of the first step, HN(SO2Cl)2 can also be obtained.
