실험 절차

3.4 ml of conc. hydrochloric acid are added to 10.1 g (34 mmol) of the compound from Example 2 and 11.6 g (102 mmol) of N-amino-4-methyl-piperidine in 100 ml of toluene AR and 50 ml of dimethylformamide and the mixture is boiled for 24 hours in a water separator. The mixture is cooled, diluted using 200 ml of ethyl acetate and extracted three times using 1N hydrochloric acid and twice using saturated sodium hydrogen carbonate solution. The organic phase is dried over magnesium sulphate and concentrated in vacuo, and the residue is chromatographed on a column (silica gel 70-230 mesh, using ethyl acetate/petroleum ether 5:95).
