of tertiary and secondary alcohols to give the corresponding alkanes is conventionally performed using an organosilane and a strong acid. In this study, a deoxygenation method was developed for tertiary and secondary alcohols, using trimethylsilane and trimethylsilyl iodide generated in situ from sodium borohydride and trimethylsilyl chloride, and trimethylsilyl chloride and potassium iodide, respectively

Provided are diphenyl sulfide derivatives which have excellent S1P3 antagonistic activity and are useful as drugs. Intensive studies have been made for the purpose of creating a compound having S1P3 antagonistic activity. As a result of the intensive studies, it has been found that diphenyl sulfide derivatives represented by general formula (1) have excellent S1P3 antagonistic activity. In general formula (1), R
1
is a hydrogen atom or the like; R
2
is an optionally substituted alkyl group having 1 to 6 carbon atoms, or the like; X is a methylene group which may be substituted with one or two fluorine atoms, or the like; Y is a hydrogen atom or the like; and Z is a halogen atom.

The present invention provides a charge transport film which is prepared through subjecting a coating film including at least one charge transporting agent to an atmospheric pressure plasma treatment, wherein electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted, and deterioration in performance due to diffusion and mixing or crystallization of low molecular weight components, such as a charge transporting agent, incorporated in a cured film is suppressed also in the case of film formation by a wet method, and which exhibits excellent charge transportability and stability over time; a production method with good productivity; and a light-emitting element and photoelectric conversion element equipped with the charge transport film, the atmospheric pressure plasma treatment being preferably a treatment that applies plasma, which is generated using a plasma generating apparatus and conveyed using an inert gas, to the coating film.
Pyridine derivatives of the formula ##STR1## wherein the ring A stands for an optionally further substituted benzene ring; the ring B stands for an optionally substituted pyridine ring; Q stands for hydroxyl group, or OQ.sup.1 or Q.sup.1 wherein Q.sup.1 stands for an optionally substituted aliphatic hydrocarbon group; and n denotes 0 or 1, or their salts, which have potassium.channel opening activity and are useful as therapeutic agents of circulatory diseases such as angina pectoris, hypertension, etc.
