Abstract
PURPOSE: To obtain the titled compound useful as an analgesic, anti-inflammatory agent, antipyretic, etc., by hydrolyzing a cyclic nitrile in the presence of a catalyst.
CONSTITUTION: A compound shown by the formula I (n is 2 or 3; R is 1W4C lower alkyl, 1W4C lower alkoxy, or phenyl which may have halogen) is hydrolyzed in the presence of a catalyst (e.g., hydrogen chloride, sulfuric acid, boron trifluoride, etc.), to give the desired compound (e.g., 4-benzoylindane-1-carboxylic acid amide) shown by the formula II. The compound shown by the formula I as a starting compound can be obtained as shown in the reaction formula.
