摘要：
R1 is -0-, -S(0)t- (where t is 0, 1 or 2), or a straight or branched alkylene chain and R2 is aryl (optionally substituted by one or more substituents selected from alkyl, alkoxy, halo, haloalkyl and haloalkoxy) or aralkyl (optionally substituted by one or more substituents selected from f alkyl, alkoxy, halo, haloalkyl and haloalkoxy) and wherein the compound of Formula (II) is a single stereoisomer or any mixture of stereoisomers. This crystalline acid is useful in treating disease-states characterized by inflammation, such as inflammatory and autoimmune disorders or pulmonary or respiratory tract inflammations in humans. Methods of preparing the crystalline acid are also described.
