A novel regiospecific C(sp3)-C(sp2) coupling between ethyl arylacetates and nitroarenes has been developed to deliver biaryl ketones in excellent yields. The protocol is metal-free, mild, and compatible with a number of functional groups on both of the reacting partners.

The present invention relates to a group of benzotriazole derivatives, infra that are potent cannabinoid-CB1 modulators (known as antagonists or inverse agonists), useful in the treatment obesity, psychiatric and neurological disorders, as well as other diseases involving cannabinoid-CB1 neurotransmission (Current Opinion in Drug Discovery and Development 2004 7(4):498-506) the pharmaceutically acceptable acid addition salts and stereoisomeric forms thereof, wherein R1 is hydrogen, halo, trifluoromethyl, C1-4alkyl, C1-4alkyloxy- or C1-4alkyloxycarbonyl; R2 is hydrogen, phenyl, C3-7cycloalkyl or C1-6alkyl optionally substituted with Ar1; R3 is hydrogen, hydroxyl or C1-6alkyl; Ar1 is phenyl or phenyl substituted with up to three halo substituents; and Het represents a monocyclic 5 or 6 membered partially saturated or aromatic heterocycle selected from furanyl, thienyl, pyrrolyl, oxazolyl, thiazolyl, imidazolyl, pyrazolyl, isoxazolyl, isothiazolyl, oxadiazolyl, triazolyl, thiadiazolyl, pyrimidinyl, pyridinyl, pyrazinyl, triazinyl, pyridazinyl, 2H-pyranyl or 4H-pyranyl wherein said heterocycle is optionally substituted with C1-6alkyl;
