Conditions
- Temperature
- 60 °C
Procedure
6 g (0.023 mol) of the product from stage 1 was introduced into 11 ml of chlorosulfonic acid in portions with cooling and under protecting gas and the mixture was heated at 60° C. for 3.5 h. The solution was added to ice, the suspension was brought to pH 8 by addition of solid sodium bicarbonate, and the precipitated product was filtered off with suction and dried under reduced pressure.
