Reaction Steps

Into a glass reactor equipped with a nitrogen inlet is charged methanol (238 ml), freshly distilled cyclopentadiene (2 moles), furfural (2 moles) and diethylamine (8 ml). The resulting reaction is slightly exothermic. The dark red solution is stirred for 71/2 hours. At this time an equal volume of distilled water is added and extracted with chloroform. The organic layer is dried and evaporated leaving a dark red viscous oil as the product, furfuryl fulvene.
