Procedure

A mixture of 1-methyl-2-vinylpyrrole (3.90 g, 36.0 mmol), α-isopropyl-α-methyl-2,5-dioxo-3-pyrroline-1-acetonitrile (7.00 g, 36.0 mmol) and chloroform is stirred overnight at room temperature and concentrated in vacuo. The resultant residue is flash chromatographed (silica gel, 50% ether:hexanes eluent) to afford the title product as a clear yellow glass (63.5 g, 58.8%).
