Abstract:
The present invention discloses (1S,5S)-3-(5,6-dichloro-3-pyridinyl)-3,6-diazabicyclo[3.2.0]heptane, salts thereof, and its use to treat pain and other disorders associated with the nicotinic acetylcholine receptor.
Abstract:
This invention is directed to processes for making substituted thiazoles. The substituted thiazole, ethyl 2-(4-hydroxyphenyl)-4-methyl-1,3-thiazole-5-carboxylate, also known as TEI-6720, is useful for treatment of gout and hyperuricemia. This compound belongs to a class of substituted thiazoles that inhibit xanthine oxidase and thus block uric acid production.
Abstract:
Disclosed is a salt of (1S,5S)-3-(5,6-dichloro-3-pyridinyl)-3,6-diazabicyclo[3.2.0]heptane, selected from the group consisting of acetate, citrate, fumarate, hemicitrate, hydrocholoride, maleate, methanesulfonate, 4-methylbenzenesulfonate, sulphate, L-tartrate and trifluoroacetate. Also disclosed is a process for preparing a compound of formula (5J) comprising the steps of a) treating compound (5D), with an aqueous acid; b) treating the mixture from step (a) with a compound of formula (A), wherein R2 is phenyl optionally substituted with alkyl, alkoxy or halo in the presence of magnesium bromide in a mixture of isopropyl alcohol and dichloromethane to provide a compound of formula (B), c) using the compound of formula (B) to prepare the compound (5J).
Abstract:
Processes are disclosed which are useful for the preparation of a substantially pure compound of formula (3), wherein R6 and R7 are each hydrogen or R6 and R7 are independently selected from (i), wherein Ra and Rb are independently selected from hydrogen, loweralkyl and phenyl and Rc, Rd and Re are independently selected from hydrogen, loweralkyl, trifluoromethyl, alkoxy, halo and phenyl; and (ii) wherein the naphthyl ring is unsubstituted or substituted with one, two or three substituents independently selected from loweralkyl, trifluoromethyl, alkoxy, and halo; or R6 is as defined above and R7 is R7aOC (O)- wherein R7a is loweralkyl or benzyl; or R6 and R7 taken together with the nitrogen atom to which they are bonded are (a) or (b), wherein Rf, Rg, Rh and Ri are independently selected from hydrogen, loweralkyl, alkoxy, halogen, and trifluoromethyl and R8 is hydrogen or -C(O)R'' wherein R'' is loweralkyl, alkoxy, benzyloxy or phenyl wherein the phenyl ring is unsubstituted or substituted with one, two or three substituents independently selected from loweralkyl, trifluoromethyl, alkoxy and halo; or an acid addition salt thereof.
