摘要:
Disclosed herein are compounds of the general Formula (I), and methods of synthesizing substituted bicyclo[1.1.1 jpentanes. The synthetic methods described herein use a [1.1.1]propellane, a Group VIII transition metal compound, a hydride source and a reagent that can contribute a substituent to form a substituted bicycIo[1.1.1 ]pentane, such as a compound of the general Formula (I).
摘要:
The present invention relates to a process for preparing gabapentin and, more particularly, it relates to a process for the direct extraction of gabapentin from an aqueous solution derived from the Hofmann rearrangement of 1,1-cyclohexanediacetic acid monoamide.
摘要:
The present invention relates to the process for the preparation of 3-amino-3- cyclobutylmethyl-2-hydroxypropionamide or an acid addition salt thereof and its further conversion into Boceprevir.
摘要:
The invention relates to compounds that are amino acid derivatives, to compositions comprising the same and uses thereof for the prevention or treatment of pain, e.g. neuropathic pain, while having neutral or beneficial effect on metabolic parameters. (Formula)
摘要:
The invention provides aminotetralin compounds of formula (I): (I) wherein R1, R2, R3, R4, R5, R6, R7, n, and m are defined in the specification, or a pharmaceutically-acceptable salt thereof, that are antagonists at the mu opioid receptor. The invention also provides pharmaceutical compositions comprising such compounds, methods of using such compounds to treat conditions associated with mu opioid receptor activity, and processes and intermediates useful for preparing such compounds.
摘要:
Method for preparing polymorph form II of gabapentin. This invention refers to an improved method for preparing polymorph Form II of gabapentin, and to the utility thereof as a starting product for the preparation of the marketed pharmaceutical speciality.
摘要:
The present invention relates to a process for the purification of Gabapentin with very low content of anions by suspending the Gabapentin acid addition salt in organic solvent and neutralizing with a base at a specified temperature range, cooling to ambient temperature, followed by separation of Gabapentin, and purification in aqueous alcohol.
摘要:
The invention provides a process for preparing gabapentin and its intermediates. The process generally involves treating gabapentin lactam with an aqueous solution of hydrobromic acid to yield gabapentin hydrobromide salt as an intermediate, which can be isolated by filtration. The gabapentin hydrobromide salt can then be hydrolyzed with a base, such as an organic amine, to yield gabapentin that can be isolated by filtration.
