If your call is "pdflatex filename.tex" I can't even see how you do the
first one automatically; could you expand on that?

Anyway, solutions include: changing your call so that it first calls
the preprocessor, then "pdflatex filename.ltx", then deletes the file;
or you can use a master file with an input file:

%%%
\documentclass{whatever}

\usepackage{preprocessor}

\begin{document}
\preprocess{filename.tex}
\end{document}
%%%

where "\preprocess" (defined e.g. in the "preprocessor" package) would
write "filename.ltx", then call "\input filename.ltx" and finally delete
the file.

You can also avoid the master/input files with a call like :

pdflatex --jobname=filename
         \documentclass{whatever}
         \usepackage{preprocessor}
         \begin{document}
         \preprocess{filename.tex}
         \end{document}

If your text editor doesn't let you customize your call to TeX that way,
well, just switch to another one :)

Best,
