合成路线1
该中间体在本合成路线中的序号：(XXIV)Alternatively, racemate (XIX) is obtained by aldol condensation of ketone (VI) with ethyl acetate (XIII) by means of LDA to yield the racemic β-hydroxy ester (XXII), which by reduction with Red-Al in toluene furnishes the corresponding diol (XXIII). Activation of diol (XXIII) with MsCl in the presence of DIEA in THF followed by cyclization by means of DIEA and MeOH in acetonitrile gives the 7-(2-naphthyl)-6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-7-ol derivative (XXIV). Finally, the N,N-diisopropyl-2-naphthamide derivative (XXVI) is treated with CH3NH2 in the presence of BuLi in THF .
