合成路线1
该中间体在本合成路线中的序号：(I)The condensation of N-(2-bromoethyl)-2-nitrobenzamide (I) with 4-(4-fluorobenzoyl)piperidine (II) by means of Na2CO3 in refluxing methyl isobutyl ketone gives N-[2-[4-(4-fluorobenzoyl)-2-piperidinyl]ethyl]-2-nitrobenzamide (III), which is reduced with H2 over Pt/C in methanol yielding the corresponding amino derivative (IV). Finally, this compound is cyclized with urea (V) in refluxing xylene.
