NOVEL METHODS AND INTERMEDIATES FOR THE PREPARATION OF (4BS,5AR)-12-CYCLOHEXYL-N-(N,N-DIMETHYLSULFAMOYL)-3-METHOXY-5A-((1 R,5S) -3-METHYL-3,8-DIAZABICYCLO[3.2.1]OCTANE-8-CARBONYL)-4B,5,5A,6-TETRAHYDROBENZO [3,4]CYCLOPROPA[5,6]AZEPINO[1,2-A]INDOLE-9-CARBOXAMIDE

摘要

The present invention provides methods and intermediates for the preparation of (1aR,12bS)-8-cyclohexyl-11-fluoro-N-((1-methylcyclopropyl)sulfonyl)-1a-((3-methyl-3,8-diazabicyclo[3.2.1]oct-8-yl)carbonyl)-1,1a,2,12b-tetrahydrocyclopropa[d]indolo[2,1-a][2]benzazepine-5-carboxamide (formula I), including pharmaceutically acceptable salts. The compound has activity against hepatitis C virus (HCV) and may be useful in treating those infected with HCV.
