実験手順

To 3-amino-4-chlorobenzenesulfonamide (420 mg) in tetrahydrofuran (2 ml) solution, ethylisocyanate (180 μl) was added and the mixture was stirred under heating and reflux for 15 hours. The reaction solution was concentrated, then the residue was recrystallized from chloroform/methanol to obtain the title compound as a crude product (550 mg).
