There are machines that do this. Prety expensive though. Maybe too expensive for a uni's department where there won't be enough work to justify the machine's price?

Not sure how flexible this one is, but it looks cheap enough for a small department to make their own sildenafil: https://science.sciencemag.org/content/363/6423/eaav2211.ful...

The yields are quite bad though AFAICT.
