  • Patent number: 7358371
    Abstract: The present invention comprises a process for the preparation of compounds that possess an affinity for the cannabinoid receptor in the human brain. These compounds are useful as immunomodulators and psychotropic agents in the treatment of thymic disorders, vomiting, myo-relaxation, various types of neuropathy, memory disorders, dyskinesia, migraine, asthma, epilepsy, glaucoma, anticancer chemotherapy, in ischemia and angina, in orthostatic hypotension and in cardiac distress. More specifically, the present invention comprises a process for the preparation of a series of compounds of formula (I): in which R1-R7 and W represent various alkyl groups and the derivatives thereof and are more specifically are defined herein.
