Reaction Steps
2-Hydroxymethyl-4-chlorosaccharin was prepared in the same manner as 2-hydroxymethyl-4-methylsaccharin, in Example 1, from 4-chlorosaccharin (1.00 g; 4.60 mmol) and formalin (37%; 3.22 ml; excess). All attempts to crystallize the viscous oily product resulted in decomposition to the starting material, and the product was thus used in the next step without characterization.
