実験手順

To a stirred solution of 2.44 parts of 2-aminoethanol in 15 parts of chloroform is added dropwise a solution of 5.6 parts of p-(2-thenoyl)hydratropoyl chloride in 15 parts of chloroform at room temperature (highly exothermic reaction). Upon completion, the whole is stirred and refluxed for 1 hour. The reaction mixture is cooled and washed with a 1N hydrochloric acid solution. The organic layer is separated, washed twice with water, dried, filtered and evaporated. The oily residue solidifies on triturating in petroleumether. The solid product is filtered off and crystallized from boiling ether, yielding N-(2-hydroxyethyl)-p-(2-thenoyl)hydratropamide; m.p. 87.1° C.
