Abstract

NEW MATERIAL:The 2-phenyl-2,3-dihydro-1,4-benzothiazine compound of formula I(R is H, lower alkyl, or lower aralkyl; Y is H, halogen or methoxy; R and Y are not H at the same time) and its salt.
EXAMPLE: 4-Ethyl-2-phenyl-2, 3-dihydro-1, 4-benzothiazine.
USE: Analgesic agent, etc. It exhibits strong activity to suppress the coagulation of blood platelet or activity to inhibit the contraction of the extracted intestine.
PROCESS: The compound of formulaIwherein R is H and Y is halogen or methoxy can be prepared by reacting the α-halogenophenylacetyl halogenide of formula II (X is halogen; Y' is halogen or methoxy) with o-aminothiophenol, and reducing the resultant 2-phenyl 2,3-dihydro-1,4-benzothiazin-3-one compound of formula III.
