Abstract

NEW MATERIAL:The compound of formulaI(R is H or lower alkyl; R<1> is lower alkyl; R<3> is cyano or lower alkoxycarbonyl). EXAMPLE:2-Imino-2H-tiino[3,2-a]indolidine-3,10-dicarboxylic acid diethyl ester. USE:Antiallergic agent, antithrombotic agent, etc. PROCESS:The 2-alkylthioindolidine compound of formula II (R<2> is lower alkyl)[e.g. 1-(2-cyano-2-ethoxycarbonylvinyl)-2-methylthioindolidine-3-carboxylic acid ethyl ester]is made to react with an acid such as concentrated hydrochloric acid at room temperature -100 deg.C. The amount of the acid is preferably equimolar or excess to the compound of formula II.
