- NOVEL AROMATIC COMPOUND AND USE THEREOF
-
Provided is a compound showing a bone formation promoting action (and/or bone resorption suppressive action). A compound of the formula (I) or a pharmacologically acceptable salt: [wherein each substituent is as defined in the DESCRIPTION], has low toxicity, shows good pharmacokinetics, has an action to promote bone formation, and is useful for the prophylaxis or To treatment of metabolic bone diseases (osteoporosis, fibrous osteitis (hyperparathyroidism), osteomalacia, Paget's disease that influences the systemic bone metabolism parameter etc.) associated with a decrease in the bone formation ability as compared to the bone resorption capacity.

- Treatment of alcohols with tosyl chloride does not always lead to the formation of tosylates
-
Treatment of substituted benzyl alcohols with tosyl chloride resulted in the formation of the corresponding chlorides, not the usual tosylates. A series of experiments demonstrated that it was possible to predict whether chlorination or tosylation would occur for substituted benzyl alcohols and pyridine methanols. Treatment of electron withdrawing group-substituted benzyl alcohols with tosyl chloride gave the corresponding chlorides in moderate yields under mild conditions, which provided a simple way to directly prepare chlorides from alcohols.
