Procedure
N-octyl-N′-phenylurea (10 g, 215 mmol) was dissolved in chlorosulfonic acid 925 g and stirred for 14 hours at ambient temperature. The reaction was poured into ice and extracted with ethyl acetate. The organic layer was washed with cold, dilute aqueous sodium bicarbonate, then dried (Na2SO4). The solvent was evaporated in vacuo to give the product as a white solid (11.46 g, 33 mmol).
