Participants

Reaction Steps

Maleic anhydride (9.8 g, 0.10 mol) and 2,3-dimethylbutadiene (9.84 g, 0.12 mol) were mixed in toluene (50 ml) for 24 h at 50° C. The solution was allowed to cool, the solvent removed in vacuo and the residue recrystallised from petroleum ether (40° C.-60° C.) to yield the title compound in 92% yield. N.m.r: δH (90 MHz, CDCl3) 2.60 (m,2H), 2.14 (m,4H), 1.74 (s,6H).
