Reaction Conditions

Reaction Steps

Hydrogen chloride gas was passed through a mixture of 54.9 g of saccharin and 500 ml of ethylene glycol for 11/2 hours. The mixture, which had warmed to 41° C., was then stirred at ambient temperature for 65 hours. The resulting solution was poured into 2 liters of ice water and the product extracted with ethyl acetate. The extracts were washed with water, dried (MgSO4), and the solvent removed under reduced pressure to give a colorless oil which slowly crystallized. The white solid was triturated with n-butylchloride to give 44.9 g of the title compound, m.p. 84°-86.5° C.
