The invention relates to the crystalline form of the free acid monohydrate of zoledronic acid, the process for preparation of the crystalline form of the free acid monohydrate of zoledronic acid, compositions containing the crystalline form of the free acid monohydrate of zoledronic acid, and the use of crystalline form of the free acid monohydrate of zoledronic acid in diagnostic methods or therapeutic treatment of warm-blooded animals, especially humans.
摘要:
A process for preparing 5-[(R)-2-(5,6-diethyl-indan-2-ylamino)-1-hydroxy-ethyl]-8-hydroxy-(1H)-quinolin-2-one salt. The process involves forming an acid salt of 5-[(R)-2-(5,6-diethyl-indan-2-ylamino)-1-hydroxy-ethyl]-8-substituted oxy-(1H)-quinolin-2-one; and converting the acid salt to a salt of 5-[(R)-2-(5,6-diethyl-indan-2-ylamino)-1-hydroxy-ethyl]-8-hydroxy-(1H)-quinolin-2-one without isolating the free base of 5-[(R)-2-(5,6-diethyl-indan-2-ylamino)-1-hydroxy-ethyl]-8-hydroxy-(1H)-quinolin-2-one.
摘要:
A process for preparing 8-substituted oxy-5-((R)-2-halo-1-hydroxy-ethyl)-(1H)-quinolin-2-ones or acceptable solvates thereof. The process involves reacting a 5-(α-haloacetyl)-8-substituted oxy-(1H)-quinolin-2-one with a reducing agent in the presence of a chiral agent and a base to form a 8-(substituted oxy)-5-((R)-2-halo-1-hydroxy-ethyl)-(1H)-quinolin-2-one, said chiral agent having a formula I or II wherein M, L, X, R1, R2 and R3 have the meanings as indicated in the specification.
摘要:
This invention relates to a hemifumarate salt of 1-(4-{1-[(E)-4-cyclohexyl-3-trifluoromethyl-benzyloxyimino]-ethyl}-2-ethyl-benzyl)-azetidine-3-carboxylic acid (Compound I), to pharmaceutical compositions comprising this salt, to processes for forming this salt and to its use in medical treatment. In addition, the present invention also relates to new polymorphic forms of the hemifumarate salt form of Compound I, as well as to pharmaceutical compositions comprising these polymorphic forms, to processes for obtaining them, and their use in medical treatment.
