    Abstract: A method of preparing a compound represented by Structural Formula (I), or a pharmaceutically acceptable salt thereof, wherein the variables of Structural Formula (I) are as described in the specification and claims, comprises the steps of: a) reacting a compound represented by Structural Formula (A) with FTNR1R7 under suitable conditions to form a compound represented by Structural Formula (B); and b) i) when R12 is -NO2, and R11 is -OR14: 1) cyclizing the compound represented by Structural Formula (B) under suitable cyclisation conditions to form a compound represented by Structural Formula (II); and 2) optionally reacting the compound represented by Structural Formula (II) with R9-LG2, wherein LG2 is a suitable leaving group, to form the compound represented by Structural Formula (I), wherein R8 is R9; or ii) when R12 is halogen, and R11 is -NHR13: 1) cyclizing the compound represented by Structural Formula (B) under suitable cyclisation conditions to form the compound represented by Structural Formula (I); and 2) optionally, when R13 is - H, reacting the compound produced from step b), ii), 1) with R9-LG2, wherein LG2 is a suitable leaving group, to form the compound represented by Structural Formula (I) wherein R8 is R9.
