The method for producing a sulfamide according to the present invention includes the step of reacting an alcohol and an oxycarbonylsulfamide compound in the presence of a trivalent phosphorus compound and an azodicarboxylic acid derivative. In one embodiment, the sulfamide is represented by Formula I, the alcohol is represented by Formula II, and the oxycarbonylsulfamide compound is represented by Formula III:
R³NHSO₂NR¹R² (I)
wherein R¹ and R² are independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl, a heterocyclic group, and alkyl substituted with the heterocyclic group, respectively, said heterocyclic group being selected from the group consisting of pyranosyl, furanosyl, piperidinyl, pyrrolidinyl, an azetidinone ring, a cephem ring, a penem ring, and a carbapenem ring; R³ is selected from the group consisting of alkyl, alkenyl, alkynyl, aralkyl, a heterocyclic group, alkyl substituted with the heterocyclic group, and pyrrolidinyl-methyl, said heterocyclic group being selected from the group consisting of pyranosyl, furanosyl, piperidinyl, pyrrolidinyl, an azetidinone ring, a cephem ring, a penem ring, and a carbapenem ring;
R³OH (II)
wherein R³ is defined as above;
R⁴OOC-NHSO₂NR¹R² (III)
wherein R¹ and R² are defined as above; and R⁴ is a carboxy protecting group.
