Yes, you have the file name in the wrong place. The syntax is "do something to FILE | pipe data to second process | pipe data to third process > redirect STDOUT to a file". What you have is "do something to STDIN | pipe data to second process | pipe data to third process but use FILE instead > redirect STDOUT to a file". You have to specify the file name on the first process in the pipeline.
