    摘要: PROBLEM TO BE SOLVED: To provide a method for industrially advantageously producing zaltoprofen as an anti-inflammatory/analgesic agent.
    SOLUTION: The method comprises the following process: Zinc iodide, sodium cyanide or potassium cyanide, and trimethylsilyl chloride are added to a compound of formula(I) followed by mixing them together to carry out a reaction to form a compound of formula(II). Sodium cyanide or potassium cyanide, trimethylsilyl chloride, acetonitrile and water are added to the compound of formula(II) followed by mixing them together to carry out a reaction to form a compound of formula(III). Polyphosphoric acid is made to act on the compound of formula(III) to effect cyclization, followed by addition of water to form a compound of formula(IV), which is then hydrolyzed to obtain the objective compound(zaltoprofen) of formula(V). In the above formulas, R is a lower alkyl.

    摘要: PURPOSE:To obtain a treating agent of hyperuricemia having low side effects specific to psychotropic agents, such as suppressive action on nervous system, comprising a dibenzothiepin (or debenzoxepin) derivative, which is novel except a part of the derivatives. CONSTITUTION:A treating agent of hyperuricemia which comprises a compound shown by formula I (Y is S or O; X is H, halogen or lower alkoxy; R is 3-4C alkylene; R and R are methyl or ethyl), such as 8-chloro-10-(3- dimethylaminopropoxy)dibenzo [b,f]thiepin or dibenzoxepin or a pharmaceutically acceptable salt as an active ingredient and can promote discharge of uric acid and urination without causing side effects such as dizziness, unsteadiness, sleepfulness, headache, weakness and malaise owing to the absence of suppressive action on nervous system frequently observed in similar well-known drug. The above-mentioned compound is obtained by reacting a compound shown by formula II with an alcohol reactive derivative shown by formula III.
