    摘要: 1,1-Di(p-fluorophenyl)urea, 2-carbobenzoxy-8-fluoro-5-(p-fluorophenyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole, an efficient process for converting the former to the latter, further comprising conversion of the latter to 8-fluoro-5-(p-fluorophenyl)-2-[4-(p-fluorophenyl)-4-hydroxybutyl)]-2,3,4,5-tetrahydro-1 H-pyrido[4,3-b]indole (flutroline) or to 8-fluoro-5-(p-fluorophenyl]-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (an alternative flutroline intermediate); and further, novel processes and intermediates used in converting the latter to flutroline.
