摘要:
This invention relates to a new process for preparation of enantiomerically pure dapoxetine or an acid addition salt thereof i.e. S(+)-N,N-dimethyl-2-[2-(naphthalenyl oxy)ethyl]benzenemethanamine hydrochoride, a potent serotonin re-uptake inhibitor (SSRI), which comprises resolving racemic (±)-dapoxetine i.e. (±)- N,N-dimethyl-2-[2- (naphthalenyloxy)ethyl] benzene methanamine with a chiral acid so as to obtain salt of the chiral acid and (+)-dapoxetine, substantially free from (-)-dapoxetine.
摘要:
The present invention provides isolated N-methyl-3-(3-methylphenoxy)-3-phenylpropylamine hydrochloride, and preparation thereof as well as of N-methyl-3-(4-methylphenoxy)-3-phenylpropylamine hydrochloride and of N-methyl-3-phenoxy-3-phenylpropylamine hydrochloride. The invention further provides the use of the above compounds as reference markers and/or reference standards during the synthesis of Atomoxetine. Also provided is a method of limiting the amounts of the impurities 3FT (3-fluorotoluene), 4FT (4-fluorotoluene), and FB (fluorobenzene) in the 2-fluorotoluene starting material used in the synthesis of Atomoxetine Hydrochloride. The purity of the Atomoxetine Hydrochloride product is ensured by determining the amounts of 3FT, 4FT, and FB in the 2-fluorotoluene starting material with the marker 3-ATM HC1.
摘要:
The invention concerns 1,7-diarylpentamethine and 1,9-diarylhetptamethine salts, in particular heptacarbon or nonacarbon carboxonium salts, and streptocyanines. The compounds correspond to the formula [G-D-G'] Q wherein Q is a strong acid anion, and G and G' represent independently of each other a OEt, amino, hydrazono, hydrazino, phosphaimino, amidino or guanidino group, or a multivalent radical optionally bound at least at one of its other ends to another group D; D represents a cationic 1,7-diarylpentamethine or 1,9-diarylheptamethine group wherein the aryl groups bear substituents representing independently of one another a hydrogen, a halogen, an alkyl radical or an alkoxy radical having 1 to 15 carbon atoms or a acetamido CH3C(O)HN- group.
摘要:
There are provided novel compounds of formula (I), wherein R , R , X, Y, V, W and Z are as defined in the specification, and pharmaceutically acceptable salts thereof, and enantiomers and racemates thereof; together with processes for their preparation, compositions containing them and their use in therapy. The compounds are inhibitors of nitric oxide synthase and are thereby particularly useful in the treatment or prophylaxis of inflammatory disease and pain.
