An efficient and simple method is introduced for the selective removal of methyl group from poly aryl-methyl ethers, in some important derivatives of benzophenones, xanthones, anthraquinones, aryl esters, benzamides and nitroanisoles with BeCl2.
This invention relates to 2-substituted-imidazo[4,5 -c]pyridines, to the process for their preparation, to pharmaceutical compositions containing said 2-substituted-imidazo]4,5-c]pyridines and to the use of said 2-substituted-imidazo[4,5-c]pyridines for modifying the balance between bone production and bone resorption in a host animal, including man.
