Description

肉桂醛的制备方法
技术领域
本发明涉及医药技术领域,具体而言,本发明涉及一种肉桂醛的制备方法。
背景技术
肉桂醛是一种重要的合成医药产品的中间体原料。
已有的肉桂醛的制备方法收率不高,合成工艺复杂,收率不稳定,需要发明一种新的制备方法,来克服已有技术的不足。
发明内容
本发明采用一种新技术,针对已有的肉桂醛的制备方法收率不高,合成工艺复杂,收率不稳定,所需原材料的采购成本高的缺点,经过长期的研发,发明了一种新的制备方法,来克服已有技术的不足,为以后的工业生产奠定了良好的技术基础。
本发明的技术方案是:
在反应器中加入1061毫克苯甲醛,加入吡啶5毫升和乙腈10毫升,搅拌中,室温中加入3毫升的乙醛,然后室温搅拌30分钟,再加入1200毫克的碳酸钾,然后持续在室温中搅拌反应2小时。反应完毕后,经后处理与纯化过程,得到化合物肉桂醛,收率为93.4%。
具体实施方式
实施例1:肉桂醛的制备:
在反应器中加入1061毫克苯甲醛,加入吡啶5毫升和乙腈10毫升,搅拌中,室温中加入3毫升的乙醛,然后室温搅拌30分钟,再加入1200毫克的碳酸钾,然后持续在室温中搅拌反应2小时。反应完毕后,经后处理与纯化过程,得到化合物肉桂醛,收率为93.4%。
实施例2:肉桂醛的制备:
在反应器中加入1061毫克苯甲醛,加入吡啶5毫升和乙腈10毫升,搅拌中,室温中加入3毫升的乙醛,然后室温搅拌30分钟,再加入1200毫克的碳酸钾,然后持续在室温中搅拌反应2小时。反应完毕后,经后处理与纯化过程,得到化合物肉桂醛,收率为90.8%。
本发明可用其他的不违背本发明的精神或主要特征的具体形式来概述。因此,无论从哪一点来看,本发明的上述实施方案都只能认为是对本发明的说明而不能限制本发明。
