실험 절차

From a solution of the sodium salt of p-(4-propyl-1-piperazinyl)benzoylacetaldehyde in 150 ml. of water (prepared from 5.7 g. of sodium methoxide in 500 ml. of tetrahydrofuran, and a solution of 24.6 g. of p-(4-propyl-1-piperazinyl)acetophenone and 8.0 ml. of ethyl formate in 100 ml. of tetrahydrofuran), 8.4 g of 2-cyanoacetamide and a solution consisting of 0.95 ml. of acetic acid, 4.0 ml. of water and 0.9 ml. of piperidine, there is obtained 6-[p-propyl-1-piperazinyl)phenyl]-1,2-dihydro-2-oxonicotinonitrile; m.p. 288°-290° (dec.).
