Use sub in case insensitive mode:

output <- sub("\\s+Bangalore$", "", input, ignore.case=TRUE)
output

[1] "TCS"                                       
[2] "Wipro global"                              
[3] "Bangalore consultant India private limited"
[4] "Infosys"                                   
[5] "systems bangalore pvt ltd"

Data:

input <- c("TCS bangalore",
           "Wipro global Bangalore",
           "Bangalore consultant India private limited",
           "Infosys Bangalore",
           "systems bangalore pvt ltd")
