Methods for making trans-(&#x2212;)-&#x394;-tetrahydrocannabinol and trans-(+)-&#x394;-tetrahydrocannabinol are disclosed herein. In one embodiment, a trans-(&#x2212;)-&#x394;-tetrahydrocannabinol composition is prepared by allowing a composition comprising (&#xb1;)-&#x394;-tetrahydrocannabinol to separate on a chiral stationary phase to provide a trans-(&#x2212;)-&#x394;-tetrahydrocannabinol composition comprising at least about 99% by weight of trans-(&#x2212;)-&#x394;-tetrahydrocannabinol based on the total amount of trans-(&#x2212;)-&#x394;-tetrahydrocannabinol and trans-(+)-&#x394;-tetrahydrocannabinol. The invention also relates to methods for treating or preventing a condition such as pain comprising administering to a patient in need thereof an effective amount of a trans-(&#x2212;)-&#x394;-tetrahydrocannabinol having a purity of at least about 98% based on the total weight of cannabinoids.

Provided are candesartan cilexetil forms and methods of their preparation. Also provided are pharmaceutical compositions prepared by combining at least one pharmaceutically-acceptable execipient with at least one candesartan cilexetil form of the invention.

Candesartan cilexetil polymorphs

Provided is a recycling process for preparing sertraline, which may be carried out on an industrial scale.

Recycling process for preparing sertraline

The invention provides a novel process for the preparation of prostaglandins and analogues thereof, and new crystalline intermediates in the process.

Process for the preparation of prostaglandin derivatives

The present invention provides a new and effective process for the synthesis of 17-phenyl-18,19,20-trinor-PGFand its derivatives, including the anti-glaucoma drugs Bimatoprost and Latanoprost. The benefit of the present invention rises inter alia from the fact that a major intermediate involved in the synthesis of the above compounds may be isolated from a mixture containing also an undesired isomer, by crystallization. In addition, the undesired isomer may be oxidized to give the starting compound, which is then recycled.

Process for the preparation of 17-phenyl-18,19,20-thinor-pgf 2a and its derivatives

The invention encompasses processes for the synthesis of cilexetil trityl candesartan from the reaction of trityl candesartan with cilexetil halide in the presence of a base and a low boiling organic solvent. Optionally, the reaction may be conducted in the presence of a phase transfer catalyst.

Preparation of candesartan cilexetil

Disclosed is a process for the preparation of the anti-glaucoma drug Latanoprost, in good yield, in large amounts and with desired purity. Also disclosed are novel intermediates for the above process.

Process for the preparation of Latanoprost

Provided are novel polymorphs and pseudopolymorphs of valacyclovir hydrochloride and pharmaceutical compositions containing these. Also provided are methods for making the novel polymorphs and pseudopolymorphs, which include valacyclovir hydrochloride monohydrate and valacyclovir hydrochloride dihydrate.

Crystalline forms of valacyclovir hydrochloride

The present invention relates to protected valacyclovir, N-tert-butoxycarbonyl-L-valine 2-[(2-amino-1,6-dihydro-6-oxo-9H-purin-9-yl)methoxy] ethyl ester, and a method of making it. The present invention further relates to a method of making valacyclovir including the steps of coupling an amine protected valine selected from N-t-butoxycarbonyl valine and N-formyl valine with acyclovir using a coupling agent to form a protected valacyclovir, and deprotecting the protected valacyclovir to form valacyclovir or a pharmaceutically acceptable salt thereof. The present invention further relates to valacyclovir in pure form, a method of making pure valacyclovir, and to compositions containing pure valacyclovir.
