실험 절차

A mixture of 1.0 g of 2,2-dimethylcyclopropanecarboxamide, 2.4 g. of 2-ketoadipic acid and 25 ml. of methyl isovalerate was heated under reflux for 4 hrs, with removal of H2O by a modified Dean-Stark trap containing molecular sieves (4A). After standing at room temperature overnight, the crystalline precipitate was filtered, washed with ether and recrystallized from ethyl acetate to give 0.23 g. of product, m.p. 163°-165°. The NMR spectrum was consistent with the desired structure.
