실험 절차
In a 3-neck 250 ml round bottom flask equipped with a short path distillation apparatus, a solution of 80.0 g of dimethyl [2-(2,2-dimethoxyethyl)-3-oxocyclopentyl]malonate and 63.0 g NMP was heated to 160° C. The solution was then charged with water until the reaction was complete. Upon completion of the reaction, distillation under vacuum (b.p.=140-145° C. at 1 mbar) of the reaction medium allowed to recover directly the purified title compound with a yield of 81%.
