该中间体在本合成路线中的序号:(III)

The reaction of 2-chloro-5-fluoro-4-(methylsulfanyl)pyrimidine (I) with N-carbethoxypiperazine (II) yields (III), which upon treatment with Raney Nickel affords ethyl 4-(5-fluoro-2-pyrimidinyl)-1-piperazinecarboxylate (IV). Hydrolysis and decarboxylation of (IV) generates 5-fluoro-2-(1-piperazinyl)pyrimidine (V). The reaction of (V) with the alpha-chloroketal (VI) generates the butyrophenone derivative (VII). Sodium borohydride reduction of (VII) and treatment with ethanolic hydrochloric acid yields BMY-14802-1.
