Objective:

To investigate the key solvents influencing the crystallization process of tofacitinib enantiomer and to explore the dominant crystal form.

Methods:

Recrystallization and suspension competition methods were used to study the crystallization of tofacitinib enantiomer in different solvents. Powder X-ray diffraction and infrared spectroscopy were used to characterize the crystalline forms of tofacitinib enantiomer. The crystal structure and crystal habit of tofacitinib enantiomer were simulated.

Results:

The tofacitinib enantiomer synthesized by ethanol was stable. The crystal characterization parameters can be used as an index to measure the raw material quality of tofacitinib enantiomer. The cell parameters of tofacitinib enantiomer are a=8.559 1, b=27.011 4, c=7.157 5, α=γ=90°, β=68.210 1, belonging to the single monoclinic system with the space group P21/c.

Conclusion:

Using ethanol as the crystallization solvent can effectively synthesize the dominant crystal form, so as to establish a crystallization process system more suitable for tofacitinib enantiomer, providing a theoretical basis and demonstration effect for the preparation of tofacitinib enantiomer.

目的:

对托法替尼SS异构体结晶工艺中的关键溶剂进行考察,探索优势晶型。

方法:

采用重结晶方法和混悬竞争方法研究托法替尼SS异构体在不同溶剂中的转晶情况,采用粉末X射线衍射和红外光谱法等多种分析方法,对托法替尼SS异构体转晶前后的结晶形式进行了结构表征。模拟托法替尼SS异构体的晶体结构和晶习。

结果:

以乙醇为结晶溶剂合成的托法替尼SS异构体较为稳定。其晶型表征参数可作为衡量托法替尼SS异构体原料质量的指标。托法替尼SS异构体晶胞参数为a=8.559 1,b=27.011 4,c=7.157 5,α=γ=90°,β=68.210 1°,属于单斜晶系,空间群为P21/c。

结论:

采用乙醇作为结晶溶剂,可以有效实现优势晶型合成,从而建立更适合于托法替尼SS异构体结晶工艺体系,为托法替尼SS异构体的制备提供了理论依据和示范参考。

目的:

对托法替尼SS异构体结晶工艺中的关键溶剂进行考察,探索优势晶型。

方法:

采用重结晶方法和混悬竞争方法研究托法替尼SS异构体在不同溶剂中的转晶情况,采用粉末X射线衍射和红外光谱法等多种分析方法,对托法替尼SS异构体转晶前后的结晶形式进行了结构表征。模拟托法替尼SS异构体的晶体结构和晶习。

结果:

以乙醇为结晶溶剂合成的托法替尼SS异构体较为稳定。其晶型表征参数可作为衡量托法替尼SS异构体原料质量的指标。托法替尼SS异构体晶胞参数为a=8.559 1,b=27.011 4,c=7.157 5,α=γ=90°,β=68.210 1°,属于单斜晶系,空间群为P21/c。

结论:

采用乙醇作为结晶溶剂,可以有效实现优势晶型合成,从而建立更适合于托法替尼SS异构体结晶工艺体系,为托法替尼SS异构体的制备提供了理论依据和示范参考。

Objective:

To investigate the key solvents influencing the crystallization process of tofacitinib enantiomer and to explore the dominant crystal form.

Methods:

Recrystallization and suspension competition methods were used to study the crystallization of tofacitinib enantiomer in different solvents. Powder X-ray diffraction and infrared spectroscopy were used to characterize the crystalline forms of tofacitinib enantiomer. The crystal structure and crystal habit of tofacitinib enantiomer were simulated.

Results:

The tofacitinib enantiomer synthesized by ethanol was stable. The crystal characterization parameters can be used as an index to measure the raw material quality of tofacitinib enantiomer. The cell parameters of tofacitinib enantiomer are a=8.559 1, b=27.011 4, c=7.157 5, α=γ=90°, β=68.210 1, belonging to the single monoclinic system with the space group P21/c.

Conclusion:

Using ethanol as the crystallization solvent can effectively synthesize the dominant crystal form, so as to establish a crystallization process system more suitable for tofacitinib enantiomer, providing a theoretical basis and demonstration effect for the preparation of tofacitinib enantiomer.
