Procedure
Using a method similar to that described by K. Hasegawa and S. Hirooka (Bull. Chem. Soc. Jap., 1972, 45, 1893), 5-(4-chlorophenyl)-3-methylsulfanyl-5,6-dihydro-4H-[1,2,4]thiadiazine 1,1-dioxide DE2 in acetone is treated with 1N NaOH and the mixture is refluxed for 2 h. The acetone is evaporated and the mixture is acidified with conc. HCl to afford the title compound DE3.
Workup
- temperaturethe mixture is refluxed for 2 h
- customThe acetone is evaporated
