Versuchsvorschrift

Using the procedure described in Example 5 but replacing 6-(2-bromoethyl)benzothiazolinone by 7-(2-bromoethyl) 2,3-dihydro 3-oxo 1,4-benzothiazine (obtained using 7-acetyl 2,3-dihydro 3-oxo 1,4-benzothiazine (described in Ann. Chem. Rome, 1955, 45, 172) treated with bromine in methylene chloride to give 7-bromoacetyl 2,3-dihydro 3-oxo 1,4-benzothiazine, then by triethysilane in acidic medium to give 7-(2-bromoethyl)2,3-dihydro 3-oxo 1,4-benzothiazine, the product of the title is obtained.
