Process for the preparation of n-propyl-n-propylidene acetamide or di-n-propyl acetamide |
| abstract |
The invention relates to a process for the preparation of n-propyl-n-propylidene acetamide or di-n-propylacetamide, according to which di-n-propyl ketone is reacted with an alkali metal cyanide or hydrocyanic acid, and the resulting di-n-propyl ketone cyanohydrin at temperatures of 20-140 ° C in the presence of concentrated mineral acids rearranged to n-propyl-n-propylidene acetamide and optionally the latter is hydrogenated to di-n-propylacetamide. With this method, pharmacologically active substances are known to be produced by simple operations. |
