  • Publication number: 20200375954
    Abstract: A therapeutic agent for impaired gastric accommodation which contains as an active ingredient a compound represented by the general formula (1): (wherein R1 represents a hydrogen atom, a hydroxyl group or a halogen atom; A represents a furyl group, a thienyl group, a thiazolyl group or an oxazolyl group; R2 and R3 each represents an alkyl group with 1 to 5 carbon atoms; and n represents an integer of 2 to 4), or an acid addition salt thereof. Use of a therapeutic agent of the present invention greatly alleviates symptoms caused by said disorders, such as early satiety and bloating, because it improves relaxation of gastric fundus and impaired gastric accommodation.

  • Patent number: 10364206
    Abstract: The purpose of the present invention is to provide a method for producing 2-halogenated benzoic acids, the method imparting high regioselectivity (high selectivity) and having a shorter reaction time than does the conventional reaction. This method for producing 2-halogenated benzoic acids, in order to achieve the above purpose, is characterized in that benzoic acids and a halogenating agent are reacted in the presence of an alkaline compound, making it possible to highly selectively obtain 2-halogenated benzoic acids.
