How set the Bibliography to the tmp folder using vim latex?

I want to a add the bibliography in to my beamer document.

Consider the tree

├── reference.bib
├── slides.pdf
├── slides.tex
└── tmp
    ├── slides.aux
    ├── slides.log
    ├── slides.nav
    ├── slides.out
    ├── slides.pdf
    ├── slides.snm
    └── slides.toc

with reference.bib

@ARTICLE{Vickrey1961,
AUTHOR = {W. Vickrey},
TITLE = {Counterspeculation, auctions and sealed tenders},
} 

and slides.tex

begin{document}
    Bla Bla cite{Vickrey1961}.
   bibliographystyle{plain}
   bibliography{reference}
end{document}

In my vimrc i have the line

 let g:Tex_CompileRule_pdf = 'mkdir -p tmp; pdflatex -output-directory tmp -interaction=nonstopmode $*; cp tmp/*.pdf .'     

which keeps my folder clean from all the other files however there seems to be problem when I want to build the bibliography.

I get the message

LaTeX Warning: Citation `Vickrey1961' on page 10 undefined on input line 155.

[10]
No file slides.bbl.
(tmp/slides.aux)

LaTeX Warning: There were undefined references.

How can is the compile command ll so that all bibliography is referenced correctly?

ltx2any -t ./tmp filename.tex
