Butyrolactone can be easily prepared from tetrahydrofuran (THF) when oxidize with Ca-hypochlorite ( Ca(OCl)2) or HNO3 as oxidizing agents.
Well may be if you start from methyl-THF...For the synthesis this you may start from furfural ( produced commercially by the acid hydrolysis of pentosan polysaccharides from non-food residues of food crops and wood wastes) then convert aldehyde CHO group to CH3(now i dont have exact idea this reaction) and of course hydrogenation of the double bonds :) Hope this compound isn't drug precursor for bad aims!
