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 Aβ 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.
公式(I)表示的4-(取代苯基)六氢吡啶[2,1-c][1,4]噁唑-6-酮或其盐是生产双环丙烯酰胺化合物的中间体,该化合物是Aβ产生抑制剂。通过将公式(II)表示的化合物或其盐经历分子内缩合反应,可以以工业上优势的方式生产4-(取代苯基)六氢吡啶[2,1-c][1,4]噁唑-6-酮或其盐。
