Compounds of formula (I) and salts and solvates are provided: wherein R6 is selected from hydrogen, halogen, C1-6alkyl, C1-6alkyl substituted with one or more fluorine atoms, C3-6cycloalkyl, C3-6cycloalkyl substituted with one or more fluorine atoms, C1-6 alkoxy, C1-6 alkoxy substituted with one or more fluorine atoms, and cyano, and Q is hydrogen or C1-6alkyl. The compounds are M1 agonists and are useful for therapy, for example in the treatment of psychotic disorders and cognitive impairment.
REACTION OF AROMATIC COMPOUNDS WITH NUCLEOPHILIC REAGENTS IN LIQUID AMMONIA. VI. ORIENTATION IN THE REACTIONS OF 2,4-DIFLUORONITROBENZENE WITH ALKALI-METAL ALCOHOLATES AND PHENOLATES

On the basis of the results from a study of the orientation during the substitution of a fluorine atom in 2,4-difluoronitrobenzene by the action of nucleophiles of the ROM type (R = Me, Et, i-Pr, Ph; M = Na, K) and its temperature dependence for the reactions with sodium methoxide and sodium phenolate in liquid ammonia at -70 to -33 deg C it was shown that the enthalpy control of the ratio of the substitution rates of the fluorine atoms at the ortho and para positions to the nitro group, which was previously found in the reactions of o- and p-fluoronitrobenzenes with sodium methoxide in liquid ammonia, is general.It was shown that the preference for substitution at the ortho position under these conditions increases with change in the nature of the alcoholate in the order MeO- - -.This is evidently due primarily to the increase in the polarizability of the alkyl group of alcoholate in the same order.
