    • A process is provided for preparing spiro-hydantoin compounds of the formula II wherein Z is N or CR4b; K and L are independently O or S; Ar is an optionally substituted aryl or heteroaryl; A2 is a linker, G′ is a linker; Q is a linker; and R2, R4a, R4c, and Rh are defined in the specification. The process optionally includes the enantiomeric separation of intermediates to allow preparation of enantiomers of the spiro-hydantoin compounds of formula II. Substituted spiro-hydantoin compounds may be prepared from the spiro-hydantoin compounds of formula II. The spiro-hydantoin compound of formula II and the substituted spiro-hydantoin compounds are useful in the treatment of immune or inflammatory diseases. Also, provided are products made by the instant inventive process and crystalline forms (prepared by any process) of the substituted spiro-hydantoin compound, 5-[(5S,9R)-9-(4-Cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.4]non-7-ylmethyl]-thiophene-3-carboxylic acid, including solvates and salts thereof, as well as methods of use thereof. Crystalline forms of certain intermediates are provided.
    • 提供了制备式II的螺 - 乙内酰脲化合物的方法,其中Z是N或CR 4b; K和L独立地为O或S; Ar是任选取代的芳基或杂芳基; A 2是连接体,G'是连接体; Q是一个连接符; 和R 2,R 4a,R 4c和R h H在本说明书中定义。 该方法任选地包括中间体的对映异构体分离,以允许制备式II的螺 - 乙内酰脲化合物的对映异构体。 取代的螺 - 乙内酰脲化合物可以由式II的螺 - 乙内酰脲化合物制备。 式II的螺 - 乙内酰脲化合物和取代的螺 - 乙内酰脲化合物可用于治疗免疫或炎性疾病。 此外,提供的是本发明方法制备的产物和取代的螺 - 乙内酰脲化合物的5 - [(5S,9R)-9-(4-氰基苯基)-3-(3, 5-二氯苯基)-1-甲基-2,4-二氧代-1,3,7-三氮杂螺[4.4]壬-7-基甲基] - 噻吩-3-甲酸,包括其溶剂合物及其盐,以及 使用它。 提供某些中间体的结晶形式。
