How can a gitalin be synthesised using reagents?

I could only found biosynthesis of gitalin rather than chemical synthesis.Biosynthesis involves enzymatic reaction. However, I wish to know how is gitalin synthesised using reagents?

Methanol, CH3OH, is a good solvent for polar substances because: (1) Methanol undergoes dipole-dipole interactions. (2) Methanol is able to form hydrogen bonds with the polar substances. (3) There are weak ion-dipole interactions in methanol. (4) The van der Waals forces in methanol cause repulsion.
