PROCESS FOR PRODUCTION OF 4-(SUBSTITUTED PHENYL)HEXAHYDROPYRIDOÝ2,1-C¨Ý1,4¨OXAZIN-6-ONE
摘要
<p>4-(Substituted phenyl)hexahydropyrido[2,1-c][1,4]oxazin-6-one represented by formula (I) or a salt thereof is useful as an intermediate for the production of a bicyclic cinnamide compound which is an A² production inhibitor. 4-(Substituted phenyl)hexahydropyrido[2,1-c][1,4]oxazin-6-one or the salt thereof can be produced in an industrially advantageous manner by subjecting a compound represented by formula (II) or a salt thereof to an intramolecular condensation reaction.</p>
