실험 절차

A mixture of ethyl 4-fluorobenzoate (4.47 g), dimethylpyrrolidin-3-ylamine (3.04 g), potassium carbonate (3.68 g) and dimethyl sulfoxide (20 ml) was heated at 130° C. for 7 hours. After cooling, the mixture was diluted with water and extracted with methyl tert-butyl ether. The organic phase was washed with water, dried over magnesium sulfate, filtered and concentrated. The product with the molecular weight of 262.35 (C15H22N2O2) was obtained in this way; MS (ESI): 263 (M+H+).
