A series of new piperidinyl- and 1,2,3,6-tetrahydropyridinyl-pyrimidine derivatives were synthesized. Among these compounds, 4-methyl-2-(1,2,3,6- tetrahydropyridin-4-yl)pyrimidine derivative 23 (SUN N5147) exhibited sub-nanomolar affinity for 5-HT1A receptor with 1000-fold selectivity over both dopamine D2 and α1-adrenergic receptors and remarkable neuroprotective activity in a transient middle cerebral artery occlusion (t-MCAO) model.

A benzoxazepine derivative having the general formula (I) and its salts and medicaments containing the same as effective ingredients: wherein, n is an integer of 2 to 5, R1indicates a hydrogen atom, halogen atom, C1to C4lower alkyl group, C1to C4lower alkoxyalkyl group, C1to C4halogenoalkyl group, cyano group, or ester group, R2indicates a hydrogen atom, halogen atom, C1to C4lower alkyl group, C1to C4lower alkoxy group, or hydroxy group, a dotted line indicates the presence or absence of a binding bond, W indicates C, CH, or CH2or a nitrogen atom, provided that, when W is a nitrogen atom, Z is bonded to W and the dotted line indicates the absence of a bond, and Z indicates an unsubstituted or substituted aromatic hydrocarbon ring group or an unsubstituted or substituted heterocyclic group). This benzoxazepine derivative and its salts are useful as medicaments for the treatment of anxiety neurosis, phobias, obsessive-compulsive disorders, schizophrenia, post-cardiac trauma stress, depression, psychosomatic and other psychoneurotic disorders, eating disorders, menopausal disorders, infantile autism and also emesis or disorders involving the cerebral circulatory system accompanying cerebral infarction and cerebral hemorrhage.
Process of production of 4-substituted-3-halogeno-1,4-benzoxazepine derivative and salts thereof
-
, (2008/06/13)
A process for producing 4-substituted-3-halogeno-1,4-benzoxazepin derivative or the salt thereof comprising: deprotonizing a benzoxazepine derivative having the formula (II): STR1 with a base; and then, reacting the deprotonized product with a phosphate halide to produce an intermediate having the formula (IV): STR2 and then, reacting the resultant intermediate (IV) with a reagent selected from (i) a complex of a phosphine with chlorine or bromine, (ii) a phosphine and a chlorine gas or liquid bromine, (iii) a phosphine and tetrachloromethane or tetrabromomethane, or (iv) a halogenated phosphite ester to produce a 4-substituted-3-halogeno-1,4-benzoxazepine derivative having the formula (I) STR3 wherein X indicates a chlorine atom or a bromine atom, or its salt.
