Preparation technology: Mizolastine pass through 100 mesh sieve; HMPCK4MCR、lactose、microcrystalline cellulose、tartaric acid pass through 100 mesh sieve; add all the materials into rapid granulator , add 10%EC alcohol solution as adhesive, obtain roundness granules; Dry them at 50℃, control moisture between 2%~3%; granulation with 18 mesh sieve; add 1% magnesium stearate and admix homogenization; pressing, hardness10kg.

制备工艺为：咪唑斯汀粉碎过100目筛，HPMC K4MCR、乳糖、微晶纤维素、酒石酸氢钾粉碎过100目筛；原辅料加入快速制粒机中搅拌均匀，加入10% EC乙醇溶液为粘合剂，制成圆整的小粒； 50℃烘干，水分控制在2%～3%之间；18目筛整粒；加入1%的硬脂酸镁混合均匀；压片，硬度10kg。

We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。
