M-Methoxyphenol

Xylamidine (87) is an amidine which serves as a serotonin inhibitor. This agent is prepared by alkylation of m-methoxyphenol with a-chloropropio-nitrile, KI and potassium carbonate in methylethyl ketone to give 85, which is in turn reduced with... [Pg.54]

This pK a is higher than would be anticipated for ortho- and meta- substituted phenols since the o meth-oxyphenol has a pK a of 9.98, m-methoxyphenol a pK a of 9.65 and resorcinol a pK a of F.81 (13). A molecular model of the drug shows that the free rotation of the phenolic hydrogen is hindered by the A -hydrogen and can explain a9-tetrahydrocannabinol s higher pK a. Of course, if solvated dimers, trimers, etc., exist with hydrophobic bonding, the observed pK a could be a hybrid pK a for a solution of such polymers. [Pg.17]

Other aryl fluoroalkanesulfonates besides trifluoromethanesulfonyl esters of phenols can be reduced to arenes. Moreover, the preparation of such esters and their reduction may be carried out in one pot . A mixture of m-methoxyphenol, perfluorooctanesulfonyl fluoride, triethylamine, dimethylformamide, for-... [Pg.911]

Anisole was hydroxylated by the ferrous ion-oxygen system in the presence of increasing amounts of added ferric ions. This resulted in a decrease rather than an increase in the proportion of m-methoxyphenol (Table XI). [Pg.268]

Derivatives of tetrafluoroiodobenzene react with terminal alkynes in the presence of a palladium-copper(I) iodide catalyst by displacement of the iodine atom (e.g. equation 7). m-Methoxyphenol condenses with phenylacetylene in the presence of the sulphonyl fluoride 54 and bis(triphenylphosphine)palladium(II) chloride to give m-methoxy-diphenylacetylene (equation 8). ... [Pg.293]
