Abstract
本发明涉及普拉格雷中间体的一种晶型,其特征在于其粉末X-射线衍射(PXRD)图在9.0±0.2、14.75±0.2、18.19±0.2和36.9±0.2°2θ处具有峰,通过本晶型有效地纯化了中间体I,大大降低了普拉格雷纯化难度。普拉格雷真正其药效的就是中间体I,因为普拉格雷盐酸盐(上市药品)到体内首先变成中间体I,而且通过此晶型有效地纯化了中间体I,大大降低了普拉格雷纯化难度。
Description
技术领域
本发明涉及普拉格雷中间体5-(α-环丙羰基-2-氟苄基)-2-氧代-2,4,5,6,7,7a-六氢噻吩并[3,2-c]吡啶的固态晶型。
技术领域
噻吩并吡啶类药物例如噻氯匹定,氯吡格雷已被用于治疗血栓的形成和相关的疾病。普拉格雷作为新一代的噻吩吡啶类口服抗血小板药物也已上市,其盐酸盐结构式如II所示,上市商品名为Effient。
EP0542411首先报道了合成普拉格雷最为重要的的方法,主要通过5-(α-环丙羰基-2-氟苄基)-2-氧代-2,4,5,6,7,7a-六氢噻吩并[3,2-c]吡啶(I)作为中间体乙酰化得到普拉格雷。
大量的专利对此工艺进行了改善,例如WO2009/062044、WO2009/066326、WO2010/060389、WO2011/110219等,它们都经历了中间体(I)制备普拉格雷,但是中间体(I)都未经分离,作为油状物或在溶液中直接乙酰化生成普拉格雷,这都加大了普拉格雷纯化的难度。
发明内容
根据现有技术的不足,本发明要解决的技术问题是:提供一种普拉格雷关键中间体5-(α-环丙羰基-2-氟苄基)-2-氧代-2,4,5,6,7,7a-六氢噻吩并[3,2-c]吡啶(I)的一种新晶型,称其为A型。
本发明解决其技术问题所采用的技术方案是:提供一种普拉格雷中间体的一种晶型,其特征在于其粉末X-射线衍射(PXRD)图在9.0±0.2、14.75±0.2、18.19±0.2和36.9±0.2°2θ处具有峰,其分子式如下I所示:
所述的X-射线衍射图在21.7±0.2、22.6±0.2、24.0±0.2、27.48±0.2、30.9±0.2、32.5±0.2、33.1±0.2°2θ处具有峰。
发现的晶型是化学纯的(通过HPLC分析,归一化纯度≥99.0%),颜色为类白色,其熔点:122.2~122.6℃。
本发明的有益效果是:通过本晶型有效地纯化了中间体I,大大降低了普拉格雷纯化难度。普拉格雷真正其药效的就是中间体I,因为普拉格雷盐酸盐(上市药品)到体内首先变成中间体I,而且通过此晶型有效地纯化了中间体I,大大降低了普拉格雷纯化难度。
附图说明
图1为5-(α-环丙羰基-2-氟苄基)-2-氧代-2,4,5,6,7,7a-六氢噻吩并[3,2-c]吡啶(I)A型的粉末X-射线衍射图。

具体实施方式
下面结合实施例对本发明做进一步描述:
实施例1
反应器内加入590ml DMF(N,N-二甲基甲酰胺),然后加入62.5g的5,6,7,7a-四氢噻吩并[3,2-c]吡啶-2(4H)-酮盐酸盐,氮气保护下,降温到0-5℃之间,加入946g无水碳酸钾,84gα-环丙羰基-2-氟苄基溴溶于530ml DMF在30-40min内滴加到反应器中,保温0-5℃反应5小时。缓慢加入900ml饱和的氯化铵溶液,600ml×3乙酸乙酯提取,有机层用饱和的氯化钠溶液(500ml×3)洗涤,干燥,减压蒸干得油状物,室温下,油状物加入适量甲苯刚好溶解得透明溶液,然后滴加环己烷至刚好变浑浊,然后降温到0-5℃搅拌3小时,过滤,真空干燥得13g类白色固体。
对上述产品做X-射线衍射(PXRD)图(谱线相对强度再括号内给出)在9.0±0.2(5.4)、14.75±0.2(24.1)、18.19±0.2(100.0)和36.9±0.2(13.7)°2θ处具有峰以及在21.7±0.2(8.4)、22.6±0.2(13.6)、24.0±0.2(16.9)、27.48±0.2(3.2)、30.9±0.2(5.0)、32.5±0.2(5.7)、33.1±0.2(3.7)°2θ处具有峰或如图1所示。
发现的晶型是化学纯的(通过HPLC分析,归一化纯度为99.3%),颜色为类白色,其熔点:122.4℃。其差示扫描量热(DSC)图和热重分析(TGA)图分别如图2和图3所示。
