摘要:
The present invention concerns novel chemical compounds corresponding to formulae (I) and (II): (I) (II) which, when marked with fluorine-18, can be used as markers of NMDA receptors for carrying out studies with a scanner.
摘要:
A method for manufacturing 3,5-dimethyl-1-adamantanamine of the present invention comprises: (i) a step of reacting 3,5-dimethyl-1-adamantanol with an acid and nitrile in an organic solvent to obtain a reaction solution; (ii) a step of adding water to the reaction solution obtained in step (i) to obtain 1-amido-3,5-dimethyladamantane; and (iii) a step of hydrolyzing 1-amido-3,5-dimethyladamantane obtained in step (ii) in the presence of an alcohol-containing solvent and an inorganic base.
摘要:
Disclosed is a method for producing a compound having an amino group and/or a hydroxyl group from a substrate compound having an atomic group containing CO or CS by eliminating said atomic group. The substrate compound having an atomic group containing CO or CS (for example, an amide, a carbamate, or the like) is allowed to react with a compound expressed by formula (I) below, at a temperature of 120°C or lower, preferably in the presence of an ammonium salt, to eliminate said atomic group containing CO or CS. In formula (I) A may not be present, and in a case where A is present, A represents an alkyl group having 1 to 6 carbon atoms.
摘要:
A process for preparing a compound of formula (V) or its enantiomer, which comprises: (a) reacting racemic aminoindan of formula (II) or its enantiomer with allylhalide in presence of a base and an organic solvent at a temperature ranging from 25 C to the reflux temperature of the solvent to give compound of formula (III) (b) reacting the compound (III) with halogenating agent in a suitable organic solvent to give a dihalo compound of formula (IV) (c) treating the dihalo compound (IV) with a suitable base to give compound (V).
