    摘要： The present invention herein provides a simple, efficient and industrially useful method for purifying an aminoacetylpyrrolidinecarbonitrile derivative which is useful as a DPP-IV inhibitor. The method comprises the steps of acting an acid such as maleic acid on an aminoacetylpyrrolidinecarbonitrile derivative represented by the following Formula 1 to form a salt, isolating the salt and then regenerating the foregoing derivative from the salt: (In the formula, A represents CH2, CHF or CF2; R represents a C1 to C6 alkyl group which may have a substitutent, a C3 to C8 cycloalkyl group which may have a substitutent, an arylmethyl group which may have a substitutent, an arylethyl group which may have a substitutent, an aromatic hydrocarbon ring which may have a substitutent, an aromatic hetero ring which may have a substitutent, or an aliphatic hetero ring which may have a substitutent; and n represents 1 or 2).
